Embedded plates with shear studs weld to beam ends. Grout fills 25mm gaps for uniform load transfer. UAE projects often require epoxy-coated connectors for desert conditions.

What are the cold climate considerations?
S355J2 grade maintains 27J impact at -40°C. Increase stiffener spacing by 1.5× in Canada/Russia. Specify low-temperature paints (ISO 12944 CX). Allow 3mm/m thermal contraction.
How are quality inspections performed?
Dimensional checks with laser trackers. UT testing for web/flange welds. Hardness testing verifies HAZ <350 HV10. 10% random destructive testing in GCC projects.
What are splice connection requirements?
Full-penetration welds with backing bars for flanges. Web bolting with 8.8S bolts. Splice plates extend 600mm beyond joints. Seismic zones require 25% overcapacity.
How does recycling work?
Scrap beams are melted in electric arc furnaces, reducing CO2 by 60% versus virgin steel. Magnetic sorting ensures purity. EU mills achieve 98% recycling rates.
