Structural applications need more than a painted surface, and this high yield prepainted galvanized coil is produced from substrate with a yield strength between 180 and 320 MPa, giving the load carrying capacity required for container plate, decking and load bearing panels. The higher strength substrate allows a thinner gauge to carry the same load, cutting weight in transport equipment and reducing the steel cost of a finished structure. Thickness runs from 0.40 mm to 1.20 mm, widths up to 1250 mm, and the coil is available in galvanized or galvalume base with a two coat paint system so the finished component needs no subsequent painting.

• High yield substrate: Yield strength between 180 and 320 MPa supports structural and semi structural use, with tested values stated per heat rather than assumed from a nominal grade.
• Thinner gauge, same load: Higher strength allows a lighter gauge to carry an equivalent load, reducing finished component weight in containers, transport equipment and modular structures.
• Container plate suitability: The mechanical profile and flatness suit container side panels, roof panels and door skins, where a painted galvanized surface must combine stiffness with corrosion resistance.
• Weld and fastener performance: The substrate is selected to remain weldable and rivetable within the specified strength range, so fabrication does not require a change of joining process.
• Decking and load bearing panels: Colour coated structural decking and load bearing wall panels can be produced directly from coil, removing a post painting step from the production route.
• Recorded mechanical data: Tensile strength, yield strength and elongation are certified per heat, giving structural designers documented input values for calculations and submittals.

Container plate, transport equipment panels, structural decking, load bearing wall panels, modular building frames, racking and shelving uprights, guard rails and industrial platform flooring are the main applications. Transport equipment makers use it for side panels and roof skins where weight reduction has a direct effect on payload and fuel consumption. Modular building producers use it for floor decking and load bearing wall panels that must be painted before assembly, and warehouse equipment manufacturers use it for shelving and racking components where stiffness per kilogram determines the design. Because the surface is already finished, the fabricated part goes straight to assembly instead of to a paint shop.

Coils are wrapped in waterproof paper and plastic film, edge protected with fibreboard rings and strapped to wooden skids suitable for container loading. Heavier coils are supplied with reinforced skids and lifting points marked on the wrap. Each label records grade, yield strength, heat number, size, coating mass, paint build and net weight. The mill certificate reports tensile strength, yield strength and elongation per heat together with zinc mass and coating thickness, and cut to length sheets or slit widths can be arranged for customers who fabricate components rather than form continuous panels. Retained samples are held for twelve months.
