The Roof Drain Parts Cast Iron Adjustable Extension is manufactured from cast iron with an EPDM gasket to provide a weather‑proof seal. Height adjustment ranges from 2‑1/8" to 3‑1/2", allowing it to fit a variety of roof membrane depths. Richang Qiaoshan Trade Co. Ltd. cites more than 25 years of experience in cast‑iron roof and floor drainage production and operates a dedicated automatic casting line.
In the drainage industry, cast iron components are valued for their rigidity and resistance to corrosion under typical outdoor conditions. Standard pressure rating for similar cast‑iron extensions is up to 1.5 bar, and they are often supplied to meet ASTM A53 or ASME specifications. Typical unit weight is around 1.5 kg, and the product is normally delivered without additional coating, relying on the material’s inherent durability.
These extensions are most frequently installed in industrial warehouses, commercial complexes and large‑scale storage facilities where reliable water removal is critical. Export is offered on FOB or CIF terms to global construction and plumbing supply markets. Prospective buyers should confirm the minimum order quantity, lead time and any required certifications before placing an order.

Before ordering, verify that the cast iron conforms to the required mechanical properties and that the EPDM gasket material meets your project's temperature and chemical exposure criteria. Request mill test reports and, if needed, a sample for dimensional inspection to ensure the 2‑1/8" - 3‑1/2" height range fits your installation envelope.
Clarify the preferred incoterm - FOB or CIF - and confirm the port of loading in China. Discuss payment terms, typically a TT advance or L/C, and ask the supplier to provide an estimated lead time based on your order volume. Shipping containers are usually filled with wooden crates to prevent damage during transit.
Arrange for a third‑party inspection before loading to verify material quality, dimensions and gasket integrity. Obtain a certificate of conformity and any applicable export documentation. Maintaining records of these checks will streamline customs clearance and downstream quality assurance.
