Import Aluminum Alloy Rain Gutter Factory — Buy in wholesale FOB from Supplier in China

Hangzhuo Moding Building Materials Co., Ltd. manufactures aluminum alloy rain gutter flanges using 6063-T5 grade material, a medium-strength alloy specifically developed for complex extruded shapes in architectural applications. This component serves as the critical connection interface between gutter channels and downspout pipes, requiring precise dimensional control to maintain hydraulic seal integrity across thermal cycling. The flange design accommodates both residential and commercial drainage system configurations. Material properties include standard yield strength of 145 MPa and ultimate tensile strength of 186 MPa, values consistent with T5 temper processing for this alloy designation.

The 6063-T5 alloy's magnesium-silicon system enables excellent extrudability for intricate flange profiles while maintaining adequate strength for mechanical joint integrity. Typical flange wall thickness ranges from 1.0 mm to 2.0 mm at connection points, with gasket seating surfaces machined or formed to ±0.25 mm tolerance for elastomeric seal compression. Industry standard flange configurations include slip-fit, bolted, and snap-lock variants, with elastomeric gasket materials typically EPDM or neoprene rated for UV and ozone exposure. Anodized surface treatments at 10-15 microns provide enhanced corrosion protection in coastal environments, while powder coating offers color integration with building facades. The alloy's thermal expansion coefficient of 23.4 x 10⁻⁶ /K requires joint design accommodation for temperature differentials.

Construction importers and building materials distributors form the primary buyer segment for this specialized drainage component. The flange's role in system integrity makes it a specification-critical item for contractors concerned with warranty exposure from water ingress damage. Unlike complete gutter systems, flange procurement often involves matching to existing channel profiles, requiring dimensional interchangeability verification. Buyers should request detailed engineering drawings from Hangzhuo Moding Building Materials Co., Ltd. showing flange geometry, fastening hole patterns, and gasket groove dimensions. Trade execution follows standard Chinese export practice with FOB or CIF terms, payment via L/C or T/T, though all commercial conditions require direct supplier confirmation.

Hangzhuo Moding Building Materials Co., Ltd. operates from Jingshan Town, Yuhang District, Hangzhou, Zhejiang Province, China, postal code 311100. The supplier carries an imported tier classification and harbor trust tier within the platform's supplier evaluation structure. Communication metrics show a 0.00 percent response rate with zero average response hours, indicating no platform-mediated buyer inquiries have generated documented replies. The company's product focus covers aluminum alloy building components, with this listing specifically addressing rain gutter flange connections rather than complete drainage systems.

The available supplier profile contains no information regarding year of establishment, factory floor area, production capacity, employee count, annual turnover, or key account relationships. No quality certifications, export credentials, or intellectual property holdings are disclosed. The location in Hangzhou places the supplier within China's eastern coastal manufacturing belt, with access to Shanghai and Ningbo ports for export logistics. Importers are advised to commission independent supplier audits or request comprehensive company documentation directly, as the platform-provided data offers limited basis for due diligence assessment.
