Products Description
Standard: China National Standard GB/T 11263-2017 (hot-rolled H-shaped steel and split T-shaped steel)
Material: Q235B
"Q" indicates yield strength, "235" indicates yield strength ≥ 235MPa, and "B" indicates quality grade (impact toughness at room temperature).
Appearance: The cross section is in the shape of the letter "H", consisting of two parallel flanges ("wings") and a web ("waist") in the middle.
Common specifications: such as H100×100×6×8 (height×width×web thickness×flange thickness, unit: mm).
Advantage
① High cost performance
Q235B is the most commonly used low-carbon steel, which is cheap and easy to purchase, suitable for budget-sensitive projects.
② Easy processing
Easy to cut/weld: low carbon content, not easy to crack during welding, suitable for on-site processing.
Quick installation: standardized size, can be directly connected by bolts or welding.
③ Balanced structural performance
Moderate bending and compression resistance, can meet most conventional construction needs.
④ Material substitutability
It can be benchmarked against Japanese SS400 and American ASTM A36, which is convenient for import and export trade.
Application
① Building structure
Factory steel frame: main beams and columns of warehouses and workshops.
Low-rise buildings: steel structure frames of residential buildings, shopping malls, and office buildings.
② Infrastructure
Temporary facilities: construction site scaffolding, construction platforms.
Bridge auxiliary structure: support for pedestrian overpasses and small highway bridges.
③ Machinery and equipment
Light equipment support: conveyor base, small crane track beam.
Agricultural facilities: greenhouse frame, agricultural machinery support frame.
④ Other fields
Container bottom plate, simple house frame, billboard support, etc.
