Rain Gutter System
Hangzhou Singer Building Materials Co., Ltd. supplies a rain gutter flange assembly kit made from either aluminium 6063‑T5 or galvanized steel G90. The kit is engineered to join standard K‑style and half‑round gutter profiles, providing a leak‑resistant joint that tolerates thermal expansion in varied climates. Each kit includes the necessary flanges, brackets and fasteners for a complete installation on residential or commercial roofs.
Aluminium 6063‑T5 offers a typical thickness of 1.2 mm and conforms to ASTM B221, delivering a lightweight yet strong component with a corrosion resistance that exceeds 30 years in most environments. Galvanized steel G90 follows ASTM A653, featuring a zinc coating of at least 90 µm that protects against rust in coastal or industrial zones. Both material options are rated for a water load of up to 250 L/min per metre of gutter, meeting standard drainage requirements.
The primary market for this system includes construction contractors, building material distributors and roofing wholesalers who need reliable, pre‑fabricated components for medium to large projects. While the listing does not disclose exact pricing, the kits are offered at competitive rates and are stocked for prompt shipment. Buyers should confirm lead times, incoterms and payment conditions directly with the supplier before finalising the purchase.

Sourcing Rain Gutter System from Hangzhou Singer Building Materials Co., Ltd. - United States Import Guide
Before confirming an order, buyers should request the material certificates for either the aluminium 6063‑T5 or the galvanized steel G90, and verify that the coating thickness and alloy composition meet the project specifications. A sample of the flange can be examined for fit with the intended gutter profile, and any required dimensions should be cross‑checked against the technical drawings supplied by the seller.
Logistics are typically arranged on an EX‑WORKS or CIF basis, but the exact incoterm must be agreed with Hangzhou Singer Building Materials Co., Ltd. Buyers need to clarify the destination port in the United States, expected lead time for kit production, and preferred payment method, which is usually an irrevocable LC or a bank guarantee. Confirming these details early helps avoid unexpected freight or customs charges.
Quality assurance should include a third‑party inspection of the finished kits, focusing on flange dimensions, coating thickness and fastener integrity. Request the inspection report and any relevant mill test certificates before releasing payment. Maintaining a record of these documents will streamline customs clearance and ensure the supplied gutter system meets the required performance standards.
