Construction & Infrastructure
Comprehensive Construction & Infrastructure Hardware
From soaring steel superstructures to cross-sea bridges, from deep-bore tunnels to high-speed rail corridors, every landmark infrastructure project depends on hardware that holds firm under extreme loads, harsh weather, and decades of service. We are a trusted supplier of heavy-duty construction and infrastructure hardware to leading contractors including China Communications Construction Company (CCCC), delivering a complete range of fasteners, rigging, and structural connection solutions engineered for the most demanding civil engineering challenges. Our products play an instrumental role in steel-box girder hoisting, on-site assembly, structural connection, and permanent installation across bridges, buildings, tunnels, highways, railways, and water conservancy projects — providing the unbreakable links that turn blueprints into reality.
Complete Product Range — Engineered for Every Phase of Construction:
High-Strength Structural Bolts — The Backbone of Steel Construction
· ASTM A325 / A490 Heavy Hex Bolts — High-strength structural bolts in Type 1 and Type 3, diameters 1/2" through 2-1/2" (M12–M64), with matching A563 heavy hex nuts and F436 hardened washers. For steel frame erection, bridge girder splicing, stadium roofs, and high-rise core structures — where joint integrity under seismic and wind loads is non-negotiable.
· ISO 898-1 / GB/T 1228–1231 High-Strength Bolts — Metric heavy hex bolts and nuts in Grade 8.8, 10.9, and 12.9, diameters M12 through M64. The standard for steel structure connection in Chinese and international infrastructure projects.
· Ordinary Hex Bolts (4.8 / 8.8 Grade) — Zinc-plated or black oxide carbon steel bolts for secondary structures, purlins, bracing, and general construction fastening.
Anchor Bolts & Foundation Hardware — Securing Every Structure to the Earth
· ASTM F1554 Anchor Bolts — Grade 36, 55, and 105 anchor bolts in L-type, J-type, and welded-plate configurations, diameters up to M100, lengths up to 3000mm. Permanently secure steel columns, crane rails, bridge bearings, equipment bases, and tower foundations to concrete — the immovable base that every structure demands.
· Embedded Parts & Precast Hardware — Pre-embedded anchor plates, lifting anchors, and threaded inserts for precast concrete elements — enabling fast, precise connection of prefabricated beams, columns, and wall panels.
Concrete & Formwork Hardware — Inside Every Pour
· Formwork Tie Rods & Waterstop Bolts — High-strength through-wall tie rods with wing nuts and walers for formwork fixation; waterstop tie rods with integrated steel water stops for basement walls, subway stations, and water-retaining structures.
· Rebar Anchorage Plates — Threaded and welded anchorage plates replacing conventional rebar hooks — reducing congestion and improving concrete flow in heavily reinforced nodes.
· Concrete Nails & Shooting Pins — Hardened steel concrete nails and powder-actuated pins for fastening wood, steel, and fixtures to concrete and masonry.
Bridge-Specific Hardware — Engineering for Spans That Defy Distance
· Steel Box Girder High-Strength Bolts — A325/A490 and 10.9/12.9 grade bolts, M20 through M30, for steel box girder segment splicing and steel truss node connections — the critical fasteners that hold long-span bridge superstructures together.
· Bridge Bearing Fasteners — Large-diameter high-strength bolts and anchor bolts for pot bearings, spherical bearings, and elastomeric bearing pads — accommodating rotation and displacement while transferring millions of kilograms of load.
· Expansion Joint Fasteners — Specialized bolts and anchoring rebar for modular and strip seal expansion joints — allowing controlled movement while maintaining a smooth riding surface.
· Cable Clamps & Suspender Hardware — Cast steel cable clamps with high-strength bolts for suspension bridge main cables; precision-threaded suspender rods and anchorage nuts for arch and tied-arch bridges.
· Bridge Maintenance & Access Rigging — Certified lifting beams, suspended access cradles, and rigging hardware for bridge inspection, painting, and repair operations.
Tunnel & Underground Hardware — Building Below the Surface
· Rock Bolts & Cable Bolts — Fully-threaded hollow grouting bolts, mechanical anchor bolts, and prestressed cable anchors for ground support in tunnels, slopes, and underground caverns.
· Steel Arch Connection Bolts — High-strength bolts with splice plates for connecting I-beam and H-section steel arches in initial tunnel support.
· Waterproofing & Drainage Hardware — Hot-melt welding washers, stainless steel insulation pins, and grouting pipe fittings for tunnel waterproofing and drainage systems.
Highway & Railway Fasteners — Connecting Nations, One Kilometer at a Time
· Guardrail Bolts — Hex bolts and splice bolts for W-beam and thrie-beam highway guardrails, plus anchor bolts for barrier posts — the safety hardware that saves lives on every highway.
· Signage & Noise Barrier Hardware — Channel bolts, band clamps, and anchor bolts for traffic sign structures, variable message signs, and acoustic barrier systems along highways and railways.
Scaffolding & Formwork Hardware — The Temporary Structures That Make Permanent Ones Possible
· Scaffolding Couplers — Right-angle couplers, swivel couplers, and sleeve couplers (EN 74 / BS 1139), forged or pressed steel, for tube-and-coupler scaffolding systems.
· Formwork Tie Rods & Accessories — High-tensile tie rods with wing nuts, walers, and spacers for wall and column formwork — reusable and engineered for concrete pressure loads.
· Adjustable Steel Props & Shoring — Heavy-duty adjustable steel shores and floor formwork supports for slab and beam construction.
General Construction Fasteners — The Small Parts That Hold Big Projects Together
· Self-Drilling & Self-Tapping Screws — DIN 7504 self-drilling screws with EPDM washers, and DIN 7981/7982 self-tapping screws — for metal roofing, wall cladding, purlins, and light-gauge steel framing.
· Blind Rivets & Huck Bolts — Aluminum, steel, and stainless steel pop rivets; Huck® ring-groove lock bolts for high-strength, vibration-resistant permanent connections.
· Welding Studs — Capacitor-discharge and drawn-arc welding studs for decking, shear connectors, and cable tray fixation.
· Stainless Steel Fasteners — A2-70 (304) and A4-80 (316) bolts, nuts, washers, and studs for curtain walls, exterior cladding, and corrosion-prone environments.
· Rebar Tie Wire & Binding Wire — Galvanized and black annealed tie wire (20#–22#) for reinforcing steel placement — a high-volume consumable on every construction site.
· Curtain Wall & Facade Hardware — Stainless steel brackets, anchor bolts, and undercut anchors for glass curtain wall and stone facade systems.
