Quality & Manufacturing
Vertically integrated production under ISO 9001:2015-aligned quality controls
One campus.
Every process.
Everwin Sports manufactures at a single vertically integrated campus in Weihai, Shandong — wire forming, welding, galvanizing, powder coating, net weaving, forging, and assembly all under one roof. Owning every process means we control every tolerance, and no critical step is outsourced to an unaudited subcontractor.
Automated powder-coating lines commissioned in 2025 expanded finishing capacity and improved coating uniformity across the marine hardware range.
In-house processes.
Wire Forming & Welding
High-tensile steel wire is formed, welded, and framed in-house — from 14-gauge basket mesh to 2" tube frames for goals and cages.
Galvanizing & Coating
Hot-dip galvanizing after fabrication, marine-grade PVC vinyl coating, and automated powder-coating lines commissioned in 2025 for uniform finishing.
Net Weaving & Finishing
Knotted nylon, knotless HDPE, and high-tenacity polyester netting woven, UV-treated, bound, and roped to sport-specific and fishery-specific patterns.
Forging & Assembly
Drop-forged shackles, swivels, and turnbuckles machined, threaded, and assembled with calibrated torque — then marked with their working load limits.
Six checkpoints.
Zero shortcuts.
Every order moves through the same documented inspection sequence — from mill certificate to loaded container.
Incoming Material Verification
Steel, wire, and netting yarn arrive with mill certificates and are sample-tested for tensile strength and composition before release to production.
In-Process Inspection
Operators and roving QC inspectors check dimensions, weld integrity, and coating thickness at every production stage — defects stop the line, not the shipment.
Proof-Load Testing
Anchors, shackles, swivels, and turnbuckles can be proof-tested to 2× rated working load before marking and packing, with records supplied on request.
Salt-Spray & UV Exposure
Coated hardware and netting samples run accelerated salt-spray and UV chamber cycles to validate corrosion protection and outdoor service life.
Final AQL Inspection
Every order passes a documented final inspection to AQL sampling standards covering dimensions, finish, marking, and packaging.
Third-Party Verification
Customer-appointed third-party inspection, including SGS, is available on any order before loading.
Controlled. Tested.
Documented.
ISO 9001:2015-aligned quality controls, ISO 14001:2015-aligned environmental practices, CE documentation support, ASTM compliance, and order-specific test reports are available for applicable orders.
