Richang Qiaoshan Trade Co., Ltd. supplies large and middle sump cast iron roof drains that feature a deep sump design for efficient rainwater collection. The drains are fabricated from cast iron, a material known for high corrosion resistance and long service life in roofing applications. Available body diameters are 15 inches, 12 inches and 8 inches, each equipped with a no‑hub outlet that simplifies installation. The product description notes that the drains may also be produced from aluminium or ductile iron, but the primary offering is cast iron.
In the construction sector, cast iron roof drains typically conform to ASTM A48 standards for gray cast iron and ASTM A536 for ductile iron, providing standard tensile strength and hardness values. A typical wall thickness for these drains ranges from 0.25 inches to 0.5 inches, delivering the structural robustness required for commercial and industrial roofs. Standard surface finish is a sand‑blasted texture that aids bonding with roofing membranes and is compatible with common gravel‑stop flashing systems.
The drains are used in commercial buildings, warehouses and industrial facilities where reliable water evacuation is critical. Buyers such as construction contractors, building developers and roofing contractors generally request ISO quality certification and may negotiate flexible minimum order quantities. The supplier lists FOB and CIF shipping options and advises that lead times depend on order size and should be confirmed during quotation. Prospective importers should verify the exact material grade, dimensional tolerances and any required accessory options before finalising the purchase.

Importers should first confirm the exact material grade - cast iron versus the optional aluminium or ductile iron variants - and verify that the chosen body diameter and wall thickness meet the project’s hydraulic calculations. Request the ASTM A48 or A536 test report and any ISO certification documents before finalising the order to ensure compliance with local building codes.
Logistics planning requires agreeing on the preferred Incoterm - FOB or CIF - as indicated by the supplier, confirming the loading port and arranging freight forwarder services. Lead times are variable; discuss production scheduling with the supplier to obtain a realistic delivery window and align payment terms such as a letter of credit or advance payment.
Quality control is best supported by arranging a third‑party inspection at the factory, reviewing the dimensional inspection report, and verifying that the sand‑blasted surface finish meets the specified texture. Importers should also obtain a mill test certificate that records material composition and mechanical properties, and ensure that all shipping documents - including the commercial invoice and packing list - are accurate and complete.
