G350 / S350GD+AZ Galvalume Steel Coil

G350 / S350GD+AZ Galvalume Steel Coil

G350 / S350GD+AZ galvalume steel coil is a medium-hard structural aluzinc material manufactured to EN 10346 standard, matching Australian G350 grade. It balances solid structural strength and reliable forming performance, sitting between DX51D+AZ soft forming grade and G550 full hard roofing grade. This grade is widely specified by engineering contractors across Europe and Australia for load-bearing cold-formed profiles, structural secondary framing and agricultural greenhouse structures.

■ Product Advantages

G350 / S350GD+AZ galvanized aluminum coil for sale, features stable yield strength, good bending resistance, and excellent anti-corrosion performance from 55% Al-Zn coating. Not too brittle like full-hard G550, not too low strength like DX51D,  making it the cost-effective picks for structural purlin and framing projects. 

If you are an engineering contractor, purlin manufacturer or greenhouse builder from Europe & Australia, contact us to get latest quotation, sample and full technical datasheet for S350GD+AZ / G350 galvalume coil.
