Galvanised Steel

Galvanised steel uses a zinc-based coating to help protect the underlying steel. Coating specification, fabrication sequence, cut-edge treatment and service exposure all affect performance.

What to specify

Include the details below so the material can be checked against the intended application and current availability.

• Product form and base-steel grade
• Coating designation or mass
• Thickness, dimensions and length
• Surface, passivation and finish requirements
• Cutting, forming, welding, quantity and certification

Applications and selection

Applications include roofing components, ducting, frames, agricultural equipment, light structures and outdoor fabrication. Exposure and maintenance conditions should be assessed for the project.

Requesting a quote

State whether the material is supplied pre-galvanised or galvanised after fabrication. Include any requirements for weld repair, cut edges and compatible fasteners.
