Product Overview
Galvalume steel sheet is aluminium-zinc coated coil that has been levelled and cut into flat sheets. It offers the same aluminium-zinc corrosion protection in a ready-to-use plate form for roofing, cladding and fabrication.

Delivery, Testing and Quality
Cold rolled and coated products are produced by Hebei Jingye High-Quality Steel Technology on a 1450 mm line. The project totals 2.6 million tonnes of annual capacity across two phases and includes a pickling tandem mill, continuous annealing and batch annealing lines, three hot-dip galvanising lines, a hot-dip aluminium-zinc line and colour coating lines. Products are manufactured under ISO 9001 and ISO 14001.
Frequently Asked Questions
What is the difference between GL sheet and GL coil?
GL sheet is the cut flat form and GL coil is the roll. They are the same aluminium-zinc coated steel in different product forms.
How does GL sheet compare with GI sheet?
GL sheet has an aluminium-zinc coating that typically lasts two to four times longer than galvanized at an equal coating weight, while GI sheet is usually lower in cost.
