Import Aluminum Flashing Boot C481 — Buy in wholesale FOB from Supplier in China

The C481 Aluminum Flashing Boot is a precision-formed aluminum alloy accessory engineered for weatherproofing pipe and vent penetrations through roofing membranes. Produced by Richang Qiaoshan Trade Co. Ltd. and shipped from Beijing, this boot integrates with cast iron soil pipe systems, flexible couplings, and roof drain assemblies to form a complete drainage protection system. The component is designed to prevent water ingress at critical penetration points where mechanical pipes or vents breach the roof envelope, with the aluminum alloy construction providing resistance to thermal cycling and atmospheric corrosion common in exposed roofing applications.

Aluminum flashing boots in the C481 class typically employ 3003 or 3004 series aluminum alloy sheet, formed to create a seamless collar with integral base flange for membrane welding or mechanical fastening. Standard thickness ranges from 0.4 mm to 1.0 mm depending on penetration diameter and wind uplift requirements, with typical flashing heights of 150 mm to 300 mm above the roof plane. The boot mates with cast iron drainage components through standard hub connections or flexible transition couplings, allowing integration with both no-hub and hub-and-spigot cast iron systems. Surface treatment is typically mill finish or clear anodised for enhanced durability in coastal or industrial atmospheres.

Applications span commercial flat roofing, institutional buildings, and multi-unit residential construction where mechanical penetrations require code-compliant weather sealing. Buyers include roofing contractors, M&E installers, and building envelope specialists procuring drainage system components for new build and refurbishment projects.
