Standard Grade 30 Gauge Plain Sheet, 50m x 1m Galvanized Roll

30 Gauge Plain Sheet

The Standard Grade 30 Gauge Plain Sheet provides a versatile and durable solution for custom metal fabrication, onsite flashing, and moisture protection in residential and commercial roofing. This 50-meter roll consists of high-quality galvanized steel designed for easy manipulation and long-term exposure to the elements. Site supervisors and roofing contractors specify this thickness for its balance of structural integrity and workability during installation.

Built for the Job

This galvanized material is a staple on construction sites for creating custom-fit accessories that standard pre-molded components cannot accommodate. The 30-gauge thickness allows tradespeople to cut the material with standard hand snips while maintaining enough rigidity to hold complex bends. By using a continuous 50-meter roll, installers significantly reduce the number of laps and joints in long valley gutters or ridge caps, which minimizes potential leak points in the building envelope.

• Custom fabrication of valley gutters and internal roof drainage channels.

• Onsite manufacturing of ridge caps, apron flashing, and barge boards.

• Lining for water tanks, ductwork components, and protective wall cladding.

Product Highlights

Corrosion Resistance

The hot-dipped zinc coating prevents oxidation and protects the underlying steel from rust in humid or coastal environments.

Fabrication Efficiency

• Thin enough for manual bending without heavy machinery.
• Roll format allows for custom length cutting to reduce site waste.

On-Site & Workshop Notes

• Always wear protective gloves when handling this metal to avoid cuts from sharp sheared edges.

• Store the roll in a dry, covered area to prevent white rust formation before installation.

• Use high-quality aviation snips for clean cuts and a folding bar for precise 90-degree bends in flashing applications.

• Ensure a minimum overlap of 150mm when joining sections in high-flow water areas like valleys.
