Import Astm Standard Asphalt Balck Paper D-4869 — Buy in Bulk from Supplier in China

ASTM D-4869 asphalt black paper is a roofing felt manufactured from organic or glass fibre mat saturated with asphalt and surfaced with mineral granules or a fine mineral coating. The source indicates roll dimensions of 36 inches by 144 feet and 36 inches by 72 feet, with compliance to both ASTM D-4869 and the heavier ASTM D-226 standards. This dual certification matters because D-4869 covers lighter-weight felt commonly used as underlayment, while D-226 governs heavier base sheets, so buyers should confirm which grade they need for their roof assembly.

The felt substrate is typically organic (wood cellulose) or glass fibre, with asphalt saturation providing the waterproofing membrane. Standard roll weights for D-4869 felt ranges from 15 to 30 pounds per square (100 sq ft), though the exact basis weight for this listing is not stated and should be confirmed with the supplier. The black colour comes from the asphalt saturant and any surface coating, which also provides UV resistance during construction exposure. Typical applications include underlayment beneath asphalt shingles, tile, slate, or metal roofing, as well as temporary weather protection during building construction.

Roofing contractors, building developers, and waterproofing specialists purchase this material for residential, commercial, and industrial projects. The supplier notes flexible minimum order quantities, though exact figures are not provided. Buyers should verify roll packaging (typical industry standard is plastic-wrapped pallets), storage requirements (keep rolls vertical and protected from moisture), and whether the product carries any additional certifications beyond ASTM compliance. The origin is Wangsi Town, Nanpi County in Cangzhou, Hebei Province, a region with established building materials manufacturing.

Cangzhou Jiansheng Building Waterproof Material Co., Ltd. is located in Wangsi Town, Nanpi County, Cangzhou City, Hebei Province, China. The supplier's tier is marked as imported with a trust tier of harbour, though the response rate shows 0.00 percent and average response hours at zero, which suggests limited transaction history or verification depth on the platform. The address places the company within Cangzhou's building materials cluster, a region known for waterproofing membrane and roofing felt production.

The listing does not disclose factory size, year of establishment, annual output, or specific export markets. No certifications beyond ASTM compliance are stated, and no client references or project portfolios are provided. Buyers should request factory audit reports, quality management system certificates, and previous export documentation before committing to large orders. The company's focus appears to be on ASTM-compliant asphalt roofing products for international trade, with flexible order quantities indicated.
