Standard, High-Strength and Custom Fasteners & Anchors for Infrastructure — One List, One Order
One mixed list, taken as one order: standard sizes to fill gaps, high-strength parts that carry the load, custom parts to your drawing. Not price — the list taken whole and the documents done right.
One China supplier for the whole list — our own production lines plus a partner ecosystem, consolidated under one desk.
- Standard families: DIN, ASTM, EN, GOST, GB, with GOST equivalents for CIS projects. Property classes 4.8 to 12.9, stainless A2 and A4.
- High-strength: structural bolting assemblies to ASTM A325/A490 and F1554, batch documents agreed per order.
- Finishes: hot-dip galvanized, zinc plated, black oxide and Dacromet.
- Adjacent hardware for infrastructure: flanges, clamps, seismic bracing, rigging and architectural hardware, supplied on the same order as fasteners.
For infrastructure, steel structure, power and petrochemical projects.
Three Buyer Lines — Steelwork, Trading and Custom Parts
Steel Fabricators & Tower Shops
- High-strength bolting assemblies — ASTM A325, A490 and F1554 structural and anchor bolts, A193 B7 studs — quoted as one matched set, bolt, nut and washer from one production lot.
- Same-lot matching is confirmed with the plant before quoting; if a size cannot be matched in the same lot, we say so on the technical reply.
- Batch documents agreed per order and written on the PO.
Fastener Traders & Stockists
- Mixed specifications, sizes, weights and quantities taken as one order — GB/T, DIN, ISO and GOST equivalents, 8.8 alongside 304/316, hot dip on part of it.
- Short lines and odd sizes assembled into one shipment and one document set, so a short line does not lose the customer.
- Send the list as it comes — no need to sort it first.
Custom Parts to Drawing
- Send a drawing or a sample — a manufacturability assessment inside 48 hours.
- Tooling quoted as a separate line, not buried in the piece price; the first round of samples is free.
- Material, grade, finish and tolerance confirmed before the production run; OEM logo and packaging to your artwork.
