Wholesale Q235 Q345 Q355 Hot Rolled Equal Unequal Angle Steel (Set 1)
Q: What's the minimum order quantity for wholesale Q235 angle steel?A: Our wholesale minimum order quantity (MOQ) for Q235 hot rolled equal/unequal angle steel is 5 tons, which balances cost-effectiveness for you and production efficiency for us. This MOQ is lower than many wholesalers (who often require 10+ tons), making it easier for small to medium businesses to access wholesale pricing. For equal angle steel (e.g., 50x50x5mm, 63x63x6mm) or unequal angle steel (e.g., 75x50x6mm, 100x63x8mm), the 5-ton MOQ can be mixed across sizes-for example, 2 tons of 50x50x5mm and 3 tons of 75x50x6mm-giving you flexibility to meet project needs. If you need a larger wholesale order (50+ tons), we offer additional volume discounts (5%-8% off), which further reduces your per-unit cost. We also waive the MOQ for repeat wholesale customers, as a way to reward long-term partnerships. The 5-ton MOQ ensures you get true wholesale pricing without overstocking, making it a practical choice for most buyers.
Q: Why choose Q345 over Q235 for wholesale unequal angle steel?A: Choose Q345 over Q235 for wholesale unequal angle steel if your projects require higher strength and durability. Q345 has a minimum yield strength of 345 MPa, which is 47% higher than Q235's 235 MPa-this means Q345 unequal angles can handle heavier, asymmetric loads (e.g., supporting industrial machinery, bridge components) without bending or deformation. Unequal angle steel is already designed for asymmetric stress, so pairing it with Q345 amplifies its performance for heavy-duty applications. Q345 also has better toughness (tested at 20°C) than Q235, reducing the risk of brittle fracture in dynamic or outdoor environments. While Q345's wholesale price is 7%-10% higher than Q235, it lets you use fewer or thinner angles (lowering total material weight and shipping costs) while maintaining safety. For wholesale orders focused on load-bearing structures, Q345 is a more reliable long-term investment than Q235.
Q: Do you offer wholesale pricing for mixed Q355 equal and unequal angle steel?A: Yes, we offer wholesale pricing for mixed orders of Q355 equal and unequal angle steel, giving you full flexibility to source all your needs in one shipment. For example, you can order 3 tons of Q355 equal angle (100x100x8mm) and 4 tons of Q355 unequal angle (125x80x10mm) and still qualify for our standard wholesale pricing (applied to the total order weight). Mixed orders simplify your procurement process-you only need to manage one order, one payment, and one delivery, instead of multiple shipments from different suppliers. We also ensure consistent quality across mixed Q355 orders: all angles undergo the same chemical composition tests (to confirm Q355's alloy content) and mechanical property checks (yield strength, tensile strength) to meet GB/T 1591 standards. For large mixed wholesale orders (20+ tons), we can customize the delivery schedule to align with your project timeline, and we provide a single consolidated invoice for easy accounting. Mixed wholesale pricing makes it easy to get exactly the Q355 angles you need at a competitive cost.
Q: What standard sizes of Q235 unequal angle steel do you have available for wholesale?A: We have a wide range of standard Q235 unequal angle steel sizes available for wholesale, covering most industrial and construction needs. Common wholesale sizes include small options like 30x20x3mm (weight: 0.72 kg/m) and 40x25x4mm (weight: 1.16 kg/m), middle sizes like 50x32x4mm (1.26 kg/m), 75x50x6mm (2.16 kg/m), and 100x63x8mm (3.98 kg/m), plus large heavy-duty sizes like 125x80x10mm (5.92 kg/m) and 160x100x12mm (8.35 kg/m). All these sizes meet GB/T 706 standards for unequal angle steel, with strict dimensional tolerances (±1mm for side length, ±0.5mm for thickness) and smooth, burr-free surfaces. We keep most of these sizes in stock, so wholesale orders can ship within 3-5 working days; for less common sizes (e.g., 140x90x10mm), we can fulfill wholesale orders within 7-10 working days with no extra cost. We provide a detailed size-weight chart for Q235 unequal angles to help you calculate wholesale quantities accurately.
Q: Can I get a sample before placing a large wholesale order of Q345 angle steel?A: Yes, we provide free samples of Q345 equal/unequal angle steel to help you verify quality before committing to a large wholesale order. Each sample is a 300mm-500mm length of your desired size-for example, a 400mm piece of 80x50x6mm Q345 unequal angle. This length is small enough to ship affordably (you only cover shipping costs) but large enough to inspect key details: you can check the surface for defects (cracks, uneven edges), measure side lengths and thickness to confirm compliance with GB/T 1591, and test weldability or rigidity if needed. Domestic shipping for samples costs $8-$15, while international shipping (via DHL/FedEx) ranges from $35-$70, depending on your location. We ship samples within 1-2 working days, so you can make a decision quickly. We guarantee the Q345 angle steel in your wholesale order will match the sample's quality-this transparency helps build trust, especially for first-time wholesale buyers.

Q: What's the lead time for a 10-ton wholesale order of Q355 equal angle steel?A: The lead time for a 10-ton wholesale order of Q355 equal angle steel depends on whether the size is in stock. For in-stock sizes (e.g., 63x63x6mm, 80x80x8mm), we can process and ship the order within 3-5 working days-this includes picking the angles from our warehouse, inspecting each bundle for quality, packaging, and arranging logistics. For non-stock sizes (e.g., 120x120x10mm), lead time extends to 7-10 working days, as we need to produce the Q355 equal angles to meet your wholesale order. This production time covers hot rolling, cooling, cutting to standard lengths (6m/9m/12m), and rigorous quality testing (chemical composition, mechanical properties) to ensure compliance with GB/T 1591. We also factor in shipping time when providing a full delivery estimate: domestic shipping (within China) takes 1-3 days, while international shipping (e.g., to Southeast Asia, Europe) takes 2-4 weeks by sea or 3-5 days by air. For urgent wholesale orders, we offer an expedited service (1-2 working days for in-stock sizes) for a small additional fee. We communicate lead times clearly upfront and provide updates if there are any delays.
Q: Is Q235 equal angle steel suitable for wholesale orders for furniture manufacturing?A: Yes, Q235 equal angle steel is an excellent choice for wholesale orders for furniture manufacturing, and it's one of our most popular wholesale products for this industry. Q235 has good ductility, making it easy to bend, cut, and drill-critical for creating custom furniture frames (e.g., table bases, chair frames, shelf supports). Its 235 MPa yield strength is more than enough to support the weight of furniture, even for heavy-duty pieces like office desks or storage cabinets. The equal L shape provides two flat surfaces for attaching wooden panels or other components, simplifying assembly for furniture factories. We offer Q235 equal angle steel in small to medium sizes (20x20x3mm to 63x63x6mm) ideal for furniture-these sizes are lightweight enough to keep furniture portable but sturdy for long-term use. Our wholesale pricing for Q235 equal angles is 10%-15% lower than retail, making it cost-effective for large furniture production runs. Whether you're manufacturing residential or commercial furniture, Q235 equal angle steel meets your needs at a wholesale price.
Q: Do you provide custom cutting for wholesale orders of Q345 unequal angle steel?A: Yes, we offer free custom cutting for wholesale orders of Q345 unequal angle steel, tailored to your project's exact length requirements. This service saves you time and labor costs, as you won't need to cut the angles on-site. We use precision CNC band saws and plasma cutters to ensure clean, accurate cuts with minimal burrs-so the cut ends are ready for welding or bolting without extra finishing. For wholesale orders, you can specify different cut lengths for different sizes: for example, 5 tons of 75x50x6mm Q345 unequal angle cut to 4.2m, and 5 tons of 100x63x8mm cut to 6.8m. The minimum custom length we can cut is 300mm, and the maximum is 12m (standard raw length). Custom cutting adds only 1-2 working days to the lead time of your wholesale order, with no extra charge. We also provide a cutting list for your records, detailing the size, quantity, and cut length of each angle in your wholesale order. This service makes our Q345 unequal angle steel even more convenient for large-scale projects.
Q: How does Q355 compare to Q345 for wholesale unequal angle steel in terms of strength?A: Q355 is slightly stronger than Q345 for wholesale unequal angle steel, making it a better choice for ultra-heavy-duty applications. Q355 has a minimum yield strength of 355 MPa, while Q345 has a minimum of 345 MPa-a small but noticeable difference that adds extra load capacity. This makes Q355 unequal angle steel ideal for wholesale orders focused on extreme-stress projects, such as large bridge supports, heavy machinery frames, or high-rise building columns. Q355 also has improved low-temperature toughness (tested at 0°C, compared to Q345's 20°C), so it performs better in cold climates. In terms of chemical composition, Q355 may contain slightly more alloying elements (like manganese) to boost its strength, which is why its wholesale price is 3%-5% higher than Q345. For most wholesale projects (e.g., general construction, industrial frames), Q345 is sufficient and more cost-effective. But if your wholesale order requires the highest possible strength for unequal angles, Q355 is the better option.
Q: Do you offer international shipping for wholesale orders of Q235 angle steel?A: Yes, we offer international shipping for wholesale orders of Q235 equal/unequal angle steel to most countries worldwide, including Southeast Asia, Europe, Africa, and North America. We work with trusted logistics partners (Maersk, COSCO for sea freight; DHL, FedEx for air freight) to provide reliable, cost-effective shipping for wholesale quantities. For large wholesale orders (10+ tons), sea freight is the most economical choice, with transit times ranging from 15-30 days depending on your location (e.g., 15 days to Thailand, 25 days to Germany). For smaller wholesale orders (5-10 tons) or urgent needs, air freight is available (3-5 days delivery) at a higher cost. We handle all export documentation for your wholesale order, including commercial invoices, packing lists, certificates of origin, and Mill Test Certificates-this ensures your Q235 angle steel clears customs smoothly. We package wholesale orders in waterproof steel bundles or wooden pallets (compliant with ISPM 15 for international shipping) to prevent damage during transit. Our international shipping service makes it easy for global buyers to access our wholesale Q235 angle steel at competitive prices.

For 50-ton orders, the discount is typically 7%-10% off our standard wholesale price, which translates to substantial cost savings for your project. This discount is higher than what we offer for smaller orders (3%-5% off for 10-20 tons) because larger volumes let us optimize production and shipping efficiency. We also waive any additional fees (e.g., custom cutting, special packaging) for 50-ton wholesale orders, further reducing your total cost. To secure the discount, you only need to confirm the order quantity and size upfront-no long-term contract required. For repeat 50-ton+ wholesale orders, we can offer an additional 2% loyalty discount, making our Q345 equal angle steel even more cost-competitive. A 50-ton order is a great way to stock up on Q345 equal angles for future projects while taking advantage of the best possible wholesale pricing.
Q: Is Q235 unequal angle steel from your wholesale suitable for outdoor use?A: Q235 unequal angle steel from our wholesale is suitable for outdoor use, but it requires a protective coating to prevent rust and corrosion, as Q235 is a plain carbon steel with no inherent rust resistance. When exposed to rain, humidity, or saltwater (e.g., coastal areas), untreated Q235 will start to rust within a few months, weakening its structural integrity. For wholesale orders intended for outdoor use, we recommend two coating options: hot-dip galvanization or anti-rust paint. Hot-dip galvanization coats the steel with zinc, extending its outdoor life to 20-30 years, and we offer this as an add-on service for wholesale orders (10%-15% extra cost). Anti-rust paint (primer + topcoat) is more affordable (5%-8% extra cost) but needs reapplication every 2-3 years. We can apply either coating to your wholesale Q235 unequal angle steel before shipping, saving you on-site treatment time. With proper coating, wholesale Q235 unequal angle steel works well for outdoor projects like garden fences, outdoor racks, or temporary construction supports.
Q: What quality checks do you perform on wholesale Q355 angle steel?A: We perform rigorous quality checks on all wholesale Q355 angle steel (equal/unequal) to ensure it meets GB/T 1591 standards and your project requirements. First, we test the chemical composition using a spectrometer to verify key elements (carbon ≤0.20%, manganese 1.00%-1.60%, silicon ≤0.55%)-this ensures the steel has the right alloy content for Q355's strength. Second, we conduct mechanical property tests: tensile tests to measure yield strength (min 355 MPa) and tensile strength (470-630 MPa), and elongation tests to confirm ductility (min 21%). For Q355, we also do Charpy V-notch impact tests at 0°C to check toughness. Third, we inspect dimensions using digital calipers and straightness gauges, ensuring side lengths, thickness, and straightness meet GB/T 706 tolerances. Fourth, we do surface inspections: each angle is checked for defects like cracks, burrs, or uneven surfaces-any non-conforming pieces are rejected. We provide a Mill Test Certificate (MTC) for every wholesale Q355 order, documenting all test results. These checks ensure your wholesale Q355 angle steel is reliable and consistent.
Q: What's the weight per meter of 50x50x5mm Q235 equal angle steel for my wholesale order?A: The weight per meter of 50x50x5mm Q235 equal angle steel is approximately 3.77 kilograms per meter (kg/m). This weight is calculated using the standard formula for equal angle steel: Weight (kg/m) = 0.00785 × Thickness (mm) × (2 × Side Length (mm) - Thickness (mm)). Plugging in the values: 0.00785 × 5 × (2×50 - 5) = 0.00785 × 5 × 95 = 3.77 kg/m. This weight is consistent for Q235 because the density of carbon steel (7.85 g/cm³) is standard. Knowing this weight is critical for your wholesale order: it helps you calculate the total weight of the order (e.g., 100 meters = 377 kg, 5 tons = ~1326 meters), which is needed for shipping cost estimates and storage planning. It also aids in structural design, as you can determine how much load each meter of angle steel can support. Our wholesale Q235 equal angle steel has an actual weight within ±2% of this theoretical value-well within industry tolerances-so you can rely on it for accurate wholesale quantity calculations.
