Import Aluminum Electrical Flashing Boot — Buy in wholesale FOB from Supplier in China

Richang Qiaoshan Trade Co., Ltd. supplies aluminum electrical flashing boots constructed from spun aluminum with integrated EPDM rubber caps, designed to create weatherproof seals around electrical conduits penetrating roof membranes. The product line includes standard, extra-wide, and extra-tall base variants to accommodate diverse roof pitches and conduit configurations, with EPDM cap sizes designated C126, C212, C412, and C481 corresponding to specific conduit diameter ranges. Spun aluminum construction provides uniform material thickness without welded seams, eliminating potential failure points from thermal cycling fatigue that affect stamped or fabricated alternatives. The EPDM compound formulation offers ozone resistance and UV stability, critical properties for roofing applications where constant exposure degrades lesser elastomers.

>EPDM cap compatibility spans multiple conduit dimensions, with the C126 typically fitting 0.5-1.0 inch trade size conduits, C212 for 1.25-2.0 inch, C412 for 2.5-3.5 inch, and C481 for 4.0 inch and larger penetrations, though buyers should confirm exact dimensional correspondence with Richang Qiaoshan. The spun aluminum base thickness, typically 0.040-0.063 inch (1.0-1.6 mm) standard for roofing flashings, determines resistance to foot traffic and mechanical damage during installation. EPDM hardness specification, measured in Shore A durometer, affects sealing compression and long-term recovery after temperature-induced compression set; typical roofing EPDM specifications call for 60-70 Shore A. The aluminum alloy used for spinning is typically 3003 or 5052-H32, offering corrosion resistance and adequate elongation for the spinning process without cracking, though Richang Qiaoshan should specify exact alloy selection.

Primary buyers include electrical contractors specialising in commercial and residential roofing, roofing material distributors, and building supply wholesalers serving climates from tropical to continental where thermal expansion and freeze-thaw cycling stress lesser flashing systems. Installation applications encompass solar panel conduit penetrations, HVAC electrical feeds, communications cable entries, and standard service mast weatherheads where code compliance with NEC Article 230 or IEC 60364 requires protected cable entries. The spun aluminum base integrates with various roofing materials including asphalt shingles, metal roofing panels, and membrane systems through appropriate underlayment and sealant selection. Trade considerations with Richang Qiaoshan include confirming whether the supplier maintains inventory of all base and cap combinations or operates on make-to-order lead times, and whether product samples are available for fit verification with specific conduit outer diameters.

Richang Qiaoshan Trade Co., Ltd. maintains a registered address at 4-3-103, Xinyuanxilizhongjie, Chaoyang, Beijing, indicating operation from a commercial or residential address within the Chaoyang district rather than a manufacturing facility. The supplier holds an organic supplier tier and voyage trust tier designation, with a zero percent response rate and zero average response hours recorded on the platform. No manufacturing certifications, factory audit reports, or production capacity figures appear in the available profile. The company name structure (trade company limited) suggests trading or distribution activity rather than manufacturing ownership, though this requires direct confirmation.

The source material references QSF as the product brand, with Richang Qiaoshan acting as the supply channel, though the exact relationship between entities is unstated. The supplier profile does not disclose year of establishment, employee count, annual revenue, or client references. Buyers should verify directly with Richang Qiaoshan whether the company maintains exclusive distribution rights for QSF products, sources on an ad hoc basis, or operates as a general trading company with multiple product lines. The Beijing address, while verifiable, does not indicate proximity to manufacturing facilities, as spun aluminum flashing production typically concentrates in industrial zones with metalworking supply chains.
