01 — Product Overview
Flashing & Accessories for Factory Roofs
Geometric Steels' flashing is designed to effectively redirect water away from seams and joints, preventing leaks and water infiltration. Flashing is applied to areas like edges, walls, corners, valleys, gutters, and downpipes — anywhere water flow could compromise the integrity of the roof.
Our flashing solutions are tailored to meet specific client needs, available in thicknesses ranging from 0.40mm to 3.00mm, with a maximum length of 5 metres.
Flashings are essential in any roofing system, as failure in these components can lead to frequent maintenance issues and water leaks. Geometric Steels understands the importance of durability and reliability, which is why we standardize flashing lengths to 5 metres for optimal performance — compared to the typical 2.5-metre market standard.

02 — The 5M Advantage
Why 5-Metre Flashing Outperforms 2.5-Metre
Geometric Steels standardizes flashing at 5 metres — double the typical market length of 2.5 metres. This single decision delivers measurable advantages across waterproofing, installation, and long-term performance.

Advantage 01
Fewer Joints
5-metre length reduces the number of joints along the flashing, minimizing potential weak points and improving leak resistance compared to 2.5-metre standard.
Advantage 02
50% Lower Leak Risk
By cutting joints by 50%, the chances of initial leakage are significantly reduced — ensuring long-term roof integrity with fewer intervention points.
Advantage 03
Reduced Lap Loss
Minimized lap loss contributes to better water management, less material waste, and improved overall value for large-span factory roof applications.
Advantage 04
Aesthetic Appeal
The seamless, long-length flashing offers a clean and aesthetically pleasing appearance — a clean roofline without excessive visible joint lines or overlaps.
Advantage 05
Customizable Design
Flashing can be customized to suit specific project requirements and design preferences — tailored to each client's exact roofing layout and needs.
03 — Application Areas
Where Flashing is Applied
Flashing is applied at every area on the factory roof where water flow could compromise the structure — providing a complete waterproofing solution from ridge to ground-level drainage.
1.
Edges
Roof edge flashing prevents water from running back under the roofing material at the eave, protecting the structural fascia and wall below.
2.
Walls
Wall-to-roof junction flashing seals the critical transition between vertical wall surfaces and the sloped roof panel, preventing water ingress at the most vulnerable intersection.
3.
Corners
Corner flashing provides watertight coverage at internal and external roof corners where two roof planes or walls meet at an angle.
4.
Valleys
Valley flashing channels high volumes of water flowing down converging roof planes, directing it efficiently to the gutters without leakage.
5.
Gutters
Gutter flashing seals the joint between the roof sheet and the gutter, preventing water from bypassing the drainage channel and infiltrating the roof structure.
6.
Downpipes
Downpipe flashing and accessories ensure a watertight connection between the gutter outlet and the vertical drainage pipe, completing the water management system.

Frequently Asked Questions
Common questions about Geometric Steels flashing and accessories for factory and industrial roofs.
Roof flashing is a thin material installed at seams and joints of a roofing system to redirect water away and prevent leaks. It is applied at edges, walls, corners, valleys, gutters, and downpipes. Failure in flashing is one of the most common causes of water leakage and frequent maintenance issues in factory roofs.
Geometric Steels flashing is available in thicknesses ranging from 0.40mm to 3.00mm, with a maximum length of 5 metres. Solutions are tailored to meet specific client requirements across all girth ranges.
Geometric Steels standardizes flashing at 5 metres — double the typical 2.5-metre market length. This reduces the number of joints by 50%, minimizing potential weak points, cutting initial leakage risk, reducing lap loss, lowering installation time, and providing a cleaner aesthetic finish on the factory roof.
Geometric Steels flashing is available in PPGI (colour-coated galvanised steel) and PPGL (colour-coated Galvalume). Both are supplied in standard 5000mm lengths in girths up to 600mm or 600–1200mm.
