Richang Qiaoshan Trade Co. Ltd. supplies round barbed stress plates that are engineered for attaching single‑ply membranes to steel and wood roof decks. The plates are fabricated from Galvalume AZ55 aluminium‑zinc coated steel, giving them a corrosion‑resistant surface. They are available in two nominal diameters, 2 inches and 2‑3⁄8 inches, each with a thickness of 0.032 inches. The barbed profile interlocks with insulation boards to prevent pull‑through under wind pressure. Packaging is 1,000 pieces per carton for efficient bulk handling.
Galvalume AZ55 is a typical coating used in roofing fasteners, meeting the ASTM A792 standard for zinc‑aluminium alloy. In the industry, round stress plates of this gauge are standard for commercial roofing in high‑wind zones, offering typical wind uplift ratings up to 150 psf. The material’s typical tensile strength exceeds 60 ksi, supporting long‑term durability. The supplier’s production line includes an automatic casting system that ensures dimensional consistency.
The plates are purchased by roofing contractors, building developers and roofing system integrators who require reliable membrane attachment. Trade terms such as FOB or CIF are negotiable, and the minimum order quantity is not disclosed in the listing, so buyers should confirm it directly. Prospective importers should verify the supplier’s certification status and request a product test report before finalising the contract.

Before placing an order, importers should request the supplier’s material test certificate to confirm the Galvalume AZ55 composition and verify compliance with ASTM A792 Grade 55. It is also advisable to obtain a dimensional inspection report that documents the 0.032 inch thickness and the exact diameters supplied. Because the supplier’s response rate is currently zero, establishing a clear communication channel and confirming the minimum order quantity will reduce the risk of mis‑alignment.
Logistics for the stress plates are typically arranged under FOB or CIF terms, but the exact incoterm must be agreed with the supplier during negotiation. Buyers should ask for an estimated lead time, as the listing does not specify production or shipping schedules. Payment methods commonly include T/T in advance or after sample approval; confirming the preferred payment schedule and any required bank guarantees will help streamline the transaction.
Quality assurance can be reinforced by arranging a third‑party inspection at the factory before loading, focusing on coating integrity, thickness uniformity and barbed profile conformity. Requesting a final product inspection report and a packing list will ensure that each carton contains the agreed 1,000 pieces. Maintaining records of the test certificates and inspection results will support customs clearance and provide assurance of compliance with project specifications.
