1. Great mechanical strength and strong clamping force, works reliably for long‑term outdoor use. Various surface treatment options help extend service life even under tough working conditions.
2. Made by precision cold bending with rolled threads. This greatly lowers thread wear and galling when you take parts apart repeatedly for equipment maintenance.
3. Consistent mechanical properties, well‑suited for general industrial projects, building construction and vehicle‑related applications.
4. Traditional U‑shape structure delivers evenly distributed clamping force. It works with regular open‑end spanners, socket wrenches, and also fits automatic assembly machines.
5. Custom sizes are available. We can adjust inner span, leg length and thread length to match special pipe sizes and limited installation space.

Application Scenarios

Commonly used for solar PV bracket fastening, outdoor municipal facilities, industrial pipe supports, environmental‑protection machinery, trailer and vehicle chassis, bridge pipe installations and general mechanical assembly work.

Note: For offshore environments with heavy chloride corrosion, we highly suggest choosing premium anti‑corrosion coating or stainless‑steel material.

Quality Control & Testing

Each production batch gets full checks including thread go‑no‑go gauging, dimension tolerance measurement and hardness sampling. Random neutral salt‑spray testing is performed to check real‑world anti‑corrosion performance. Raw‑material composition can be confirmed via spectrum analysis. Mill test certificates and third‑party SGS inspection reports can be supplied for bulk orders. Our whole production runs under ISO9001 quality‑management requirements.

Packing, Storage & Shipment

Standard packing: inner moisture‑proof PE bags + outer woven bags, loaded on pallets for sea freight. Small‑volume orders can use cartons, and custom shipping marks are acceptable.
Please store goods in dry, well‑ventilated warehouses. Keep away from dampness and corrosive dust for long periods to prevent surface rust.
We support multiple trade terms including FOB, CIF and DDP, and keep steady lead‑time for shipments.

After‑sales & Technical Support

Our pre‑sales team can advise proper material and surface finish based on your site conditions and local climate. If manufacturing defects are found after goods arrive, we offer free replacement and cover related shipping costs.
