Can clamp couplers be customized?

Yes, manufacturers offer custom clamp couplers for specialized needs, including non-standard jaw sizes, special surface treatments (epoxy, duplex galvanizing), custom bolt lengths, and integral features like lifting eyes.

What is the typical lifespan of a clamp coupler?

Forged Galvanized Steel: 10-15 years in mild environments, 5-8 years in coastal areas. Stainless Steel: 20+ years. Pressed Steel: 3-5 years for light-duty use. Lifespan is reduced by improper storage, overloading, or lack of maintenance.

AI-Powered supplier vetting

SummaryWeifang Shengao Machinery Co., Ltd. is a limited company focused on mechanical parts, hardware, metal tools, CNC machine tools, and related components. It identifies as a professional technical supplier and offers 3D software design and broad customization services, including sample-, design-, full-, minor-, and flexible customization. The supplier has written procedures and records for service assessment, corrective actions, and complaint handling. Its export sales share is stated at 71%–90%, with three years of export experience. However, the supplier has nine employees, only two years of total R&D engineer experience, no new products in the past year, no ODM, SDK, or overseas service infrastructure, and no stated customer cases. Audit information is provided for a TUV Rheinland audit with a validity period from September 4, 2025 to September 3, 2026, but the evaluation result is recorded as 0 and no certification name is specified.

Supplier typeThe supplier explicitly identifies as a professional technical supplier and a limited company. Its stated business and product scope covers mechanical parts, hardware products, metal tools, CNC machine tools, functional components, forgings, and powder metallurgy products; the audit record identifies mechanical parts as the primary product.

After-Sales capabilityThe supplier has clear written procedures and followed records for corrective and preventive actions and for handling customer complaints. This directly supports an established service-response process, although the slices do not provide service performance results or response-time data.

Production capacityThe supplier reports an annual production output range, six to ten quality-control staff, on-time delivery, random production quality inspection, and its own factory. It has nine total employees, so the available evidence supports an operating production capability, while capacity beyond the stated output range cannot be determined.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, and also welcomes OEM and ODM requests according to its company description. These repeated statements provide direct evidence of broad customization coverage, although the separate record states that ODM is not available, creating a conflict on ODM specifically.

Product Q&A

Q:What is a clamp coupler?

A clamp coupler is a forged or pressed steel fitting designed to securely fasten two scaffolding tubes together, either in parallel, perpendicular, or angled configurations. It transfers loads (tension, compression, shear) between tubes, maintaining the rigidity and safety of scaffolding or formwork support systems. Unlike standard clamps, couplers are engineered for heavy structural use and comply with strict industry standards (e.g., EN 74, BS 1139).

Q:What materials are clamp couplers made of?

Common materials include Forged Carbon Steel (Q235, Q345, 45# Steel) for high strength, Pressed Steel for cost-effective light-to-medium duty, and Stainless Steel (304/316) for corrosion resistance. Surface treatments include hot-dip galvanizing, powder coating, or zinc plating to prevent rust.

Q:What is the load capacity of a clamp coupler?

Load capacity depends on material and type. Right-Angle/Forged Couplers: Shear 8-12 kN, Tensile 6-8 kN. Swivel Couplers: Shear 6-10 kN. Pressed Couplers: Shear 3-5 kN. Most couplers have a minimum safety factor of 4:1.

Q:What maintenance practices ensure the longevity of clamp couplers?

Clean after use with a wire brush or pressure washer. Apply anti-corrosive lubricant to bolt threads. Regularly inspect for cracks or deformation. Store in dry, ventilated areas. Touch up damaged galvanized areas with zinc-rich paint.

Q:What safety precautions must be followed when using clamp couplers?

Never use damaged or non-compliant couplers. Always use a torque wrench. Do not exceed rated load capacity. Ensure tubes are straight and undamaged. Wear PPE during installation. Hire certified scaffolders for high-rise systems.
