What materials and specifications are used?

Body and jaws are made of high-tensile steel (Q345B/S355JR), drop-forged for strength. Bolts are Grade 8.8+ alloy steel. Standard surface treatment is Hot-Dip Galvanized.

Does it damage the beam flange?

The hardened serrated jaws create a mechanical grip by slightly indenting the surface. This causes superficial marks but does not compromise the beam's structural integrity.

What is your MOQ (Minimum Order Quantity)?

Standard C-Tiger Clamps have an MOQ of 100 pieces. Customized or large project orders have negotiable MOQs. Samples are available for testing.

What is the production lead time?

Samples take 10-15 working days. Standard orders take 20-30 working days. Custom orders take 35-45 working days after confirmation.

Can it be used on rounded surfaces or pipes?

It is optimized for flat, parallel surfaces like I-beam flanges. Effectiveness on round pipes is reduced; dedicated couplers are recommended for round tubes.

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 C-Tiger Clamp?

A C-Tiger Clamp is a heavy-duty steel clamping device with a 'C' shape and serrated jaws, used to securely connect steel beams, pipes, or timber without drilling or welding.

Q:What are the primary applications?

It is used for scaffolding, formwork support, steel erection, stage rigging, and general industrial clamping where a strong, removable grip is needed.

Q:What are the advantages over welding or drilling?

It offers speed (installation in minutes), reusability, no damage to structural members, versatility across beam sizes, and enhanced safety by eliminating fire risks.

Q:What sizes and capacities do you offer?

Flange thickness capacity ranges from 6mm to 30mm+. Safe Working Load (SWL) varies from 15 kN to 50 kN per clamp, depending on the model and installation.

Q:How is it installed and tensioned?

Position the upper jaw over the beam, close the lower jaw, insert the clevis pin, and tighten the tensioning bolt with a wrench until the specified torque is reached.
