Import 5.2inch Pvc Rain Gutter — Buy in wholesale FOB from Supplier in United States

The 5.2-inch PVC rain gutter from Hangzhou Singer Building Materials Co., Ltd. is a dual-wall drainage component manufactured from a PVC/ASA blend with 68-70% PVC content, engineered for residential and commercial roofing systems. It is available in K-type and square profiles, with standard gutter dimensions of 130 by 85 by 105 millimetres at 3.4 millimetres wall thickness, and downspout dimensions of 86 by 63 millimetres at 1.9 millimetres thickness. Standard lengths run 3, 4, or 5 metres, though custom lengths are available on request. The product carries ISO9001 and SONCAP certifications and is rated for environmental temperatures between minus 40 degrees Celsius and 75 degrees Celsius, with a 20-year warranty against material failure.

The PVC/ASA blend was selected for its proven performance in tropical and subtropical climates where UV degradation and thermal expansion challenge pure PVC formulations. ASA, or acrylonitrile styrene acrylate, provides surface colour stability and impact resistance without requiring painting, a common cost adder for metal alternatives. The dual-wall construction, specifically the dural gutter wall design referenced in the product literature, creates an air gap that reduces thermal bridging and condensation risk compared to single-wall extrusions. Standard colour options include brown, white, and black, with custom colour matching available for volume orders. The 68-70% PVC content range reflects typical compound formulations for this product class, balancing rigidity, cost, and processability in extrusion manufacturing.

This gutter system targets building material distributors, construction contractors, and property developers in markets including Thailand, Kenya, and Ghana, where cost-effective drainage solutions are prioritised alongside installation speed. The K-style profile, with its decorative ogee front face, carries approximately twice the hydraulic capacity of equivalent U-shape systems and provides a more secure rectangular downspout interface. Installation requires no specialist tools or seam-forming equipment, reducing labour cost versus metal systems. Buyers should confirm exact MOQ, pricing, and Incoterms directly with Hangzhou Singer Building Materials Co., Ltd., as these trade terms are not specified in the available listing data.

Hangzhou Singer Building Materials Co., Ltd. lists its address as Floor 15, Building C, Wanda Plaza, Shixiang Street, Gongshu District, Hangzhou, Zhejiang, 310000, with the origin country noted as United States. The supplier holds a harbor trust tier on the platform and shows a response rate of 0.00% with an average response time of zero hours, indicating no recorded inquiry responses within the available data window. This profile does not state year of establishment, production floor area, employee count, annual revenue, or verified export markets beyond the product description's reference to Thailand, Kenya, and Ghana as destination examples.

The company's product focus centres on PVC rain gutter systems and related roofing drainage components, with this 5.2-inch dual-wall gutter positioned as a volume export item. No information is provided about in-house extrusion capability versus outsourcing, R&D staffing, or quality control protocols beyond the ISO9001 certification. Buyers should verify factory audit status, production capacity per month, and whether the United States origin designation reflects manufacturing location, trading office function, or corporate registration. The lack of response history suggests direct contact through the listed address or alternative channels may prove more reliable than platform messaging.
