"We switched to Jinzehong for our multi-state retail chain roofing program. The custom-width TPO membrane reduced seam labor by 20%, and the direct pricing saved our portfolio over $250,000 annually. Their documentation made approvals straightforward."
– John M., Director of Facilities, US-Based Retail Group

Yes. Our OEM/ODM service specializes in this. We adjust polymer formulas and additives to meet specific ASTM E84 Class A or Class B requirements and can match any Pantone color for aesthetic or heat-reflectivity purposes.
We provide free A4-sized material samples of our standard or proposed custom blends. Courier delivery to the USA takes 3-5 business days via DHL/UPS.
The standard MOQ is one 20-foot container to ensure cost efficiency. For trial orders or specific custom materials, we can discuss a lower MOQ, typically starting from 1,000 square meters.
Every batch undergoes 5-point QC: raw material inspection, in-process thickness/tensile checks, final product testing, roll inspection, and pre-shipment audit. We provide test reports. In the rare event of a verified manufacturing defect, we commit to replacement or compensation as per our warranty terms.
Michael T., Project Manager (Texas, USA): "Used their HDPE liner for a large retention pond. The material was consistent across all rolls, and the welding was straightforward. Saved about 35% compared to our previous supplier with no quality drop. Will reorder."
Sarah L., Architectural Specifier (Ontario, Canada): "Their technical team was responsive. We needed a custom-reinforced PVC for a museum green roof. They provided full calculation reports and mock-ups, which helped get the spec approved. The project was completed 18 months ago and is performing perfectly."
David K., Wholesale Distributor (Florida, USA): "We import and stock Jinzehong's TPO membranes. The quality is on par with major brands. Our contractor clients appreciate the cost savings and reliability. The factory's communication on stock levels and shipping is excellent, which helps us plan our inventory."
