These U‑bolt are manufactured in-house at Guojian Steel’s own fastener workshop; our product range includes standard U-bolts, custom-shaped U-bolts, and U-shaped pipe clamps. They are designed to resolve common on-site issues such as pipe slippage, loose bracket connections, and insecure equipment clamping. As a direct manufacturer with no middlemen, we ensure precision threading, consistent tensile strength, and a choice of anti-corrosion finishes. We accommodate orders of all sizes, conduct rigorous factory inspections, and offer fast turnaround times. Our products are widely used in photovoltaic projects, mechanical and electrical piping, steel structure installations, and municipal utility pipeline projects.
Common Types: Standard U‑bolt, U-clamps, extended U-bolts, custom-bent U-fasteners, and U-bolts with backing plates; available as complete sets including matching nuts and washers.
Raw Materials: Q235B carbon steel and Q355B high-strength steel; stainless steel options are also available upon request. Incoming materials undergo rigorous screening to ensure quality and eliminate substandard stock.
Surface Anti-Corrosion Treatments: Various processes available—including natural black finish, electro-galvanizing, hot-dip galvanizing, thermal diffusion galvanizing (Sherardizing), and Dacromet coating—suitable for dry indoor, exposed outdoor, and humid/corrosive environments.
Manufacturing Precision: Produced via cold-bending and thread rolling; features uniform thread profiles and excellent interchangeability. Hole diameters and bending radii are strictly controlled to ensure a precise, snug fit during installation.
Specification Range: Supports standard GB (National Standard) stock items; custom dimensions for bending radii, shank lengths, and thread specifications are available based on pipe or rod diameters.
Strong Clamping and Locking Capability: The U-shaped wrap-around design provides a large contact area with the rod or pipe; once tightened, the fastener resists slipping or shifting, minimizing the risk of loosening over time.
Stable and Reliable Tensile Strength: Precision bending ensures a crack-free, defect-free structure with uniform load distribution, meeting the fastening load requirements for photovoltaic systems, piping, and steel structures.
Excellent Corrosion Resistance: A range of anti-corrosion treatments slows the rate of rusting during long-term outdoor use, thereby reducing the frequency of maintenance and replacement.
Broad Compatibility: Compatible with standard pipes and structural steel sections, while also supporting custom sizing for non-standard dimensions; a single product type can accommodate the clamping and securing of various engineering components.
Convenient and efficient installation: Supplied as a complete, ready-to-use set; assembly requires only the attachment of nuts and washers on-site. No secondary on-site bending or processing is needed, saving construction time and labor.
In-house fastener production: Guojian Steel operates a dedicated fastener processing unit. The entire U‑bolt manufacturing process—from raw material cutting and bending to thread rolling and anti-corrosion treatment—is completed internally without outsourcing.
Dual production model (Stock + Custom): Large inventories of standard specifications are maintained for rapid dispatch of urgent orders; custom production based on drawings or samples is available for non-standard shapes and sizes.
Strict factory inspection process: Random inspections cover bending appearance, thread fit (go/no-go gauges), dimensional tolerances, and coating quality; non-conforming products are screened out before packaging and shipment.
Orders of all sizes accepted: Capable of handling both large-volume project stocking and small-batch replenishment orders, with flexible scheduling to ensure timely delivery.
Ordering methods: Supports bulk procurement, wholesale of stock items, small-batch replenishment, and custom production based on drawings or samples. Rapid quotes are available upon provision of pipe diameters, rod dimensions, or technical drawings.
Customization options: Customizable material, bending radius, rod length, thread specifications, and anti-corrosion treatments; complete sets including nuts, flat washers, and spring washers are available.
Packaging and shipping: Items are packed by category and specification with protective measures to prevent thread damage; bulk shipments are handled via full truckload, while smaller orders can be shipped via logistics or express courier.
Delivery Services: Factory documentation regarding material specifications is available; specification verification is supported, with open communication to resolve any machining deviations; selection consultation is provided to assist customers in choosing the right specifications.

Question |
Answer |
|
Can U-bolts be made in custom or non-standard sizes? |
Yes; the bending diameter, total shank length, and thread specifications can be adjusted based on pipe outer diameter and installation space requirements. Manufacturing is available based on provided drawings or samples. |
|
Which anti-corrosion treatment should be chosen for outdoor use? |
For outdoor/exposed environments, hot-dip galvanizing or thermal diffusion galvanizing is recommended; for dry indoor environments, electro-galvanizing or a black oxide finish is suitable. |
|
Do the U-bolts come with nuts and washers? |
They can be supplied as a complete set including nuts and washers, or the bolt body can be purchased separately; simply specify your requirements when ordering. |
