FAQs – What Customers Ask Most !
Your detailed FAQ resource for Galvanized U‑Bolt answers high-intent queries related to performance, sizing, certification, installation, and procurement—trusted information tailored for B2B and institutional buyers seeking secure, durable fastening solutions.
What is a Galvanized U‑Bolt and what is it used for?
A Galvanized U‑Bolt is a U-shaped threaded fastener coated with zinc for corrosion resistance. It clamps pipes, beams, cables, or round profiles to a support structure across industrial and infrastructure applications.
What sizes of Galvanized U‑Bolt are available?
Galvanized U‑Bolts typically range from thread M6 to M20 (or ¼″ to ⅝″), and inner diameters covering nominal pipe sizes from ½″ up to 16″ or more to fit diverse project needs.
How is a Galvanized U‑Bolt measured accurately?
Key parameters include inside diameter (distance between legs), inside height (or depth), thread size and length. Measurement templates or vernier calipers ensure specs match installation requirements.
Is the Galvanized U‑Bolt corrosion-resistant for outdoor use?
Yes, the zinc-coating (zinc plate or hot-dip galvanized) provides strong rust protection, ensuring long-term performance even in humid, coastal, and outdoor infrastructure environments.
What load capacity can a Galvanized U‑Bolt support?
Load capacity depends on thread size, material grade and galvanizing. Typical grades offer high tensile strength compliant with DIN/ISO standards; manufacturers provide graded load data.
Can a Galvanized U‑Bolt meet government tender specifications?
Yes. These U‑Bolts can be ISI/BIS compliant and manufactured per DIN, ISO or ASTM standards, making them eligible for municipal/government infrastructure and EPC procurement.
How should a Galvanized U‑Bolt be installed for optimal performance?
Installation involves matching bolt size to pipe/beam, aligning via template, torquing nuts uniformly, and using appropriate washers and saddle plates for load distribution.
How long does the zinc coating on a Galvanized U‑Bolt last?
The lifespan depends on environmental exposure and thickness of galvanizing. Hot-dip galvanizing typically endures years of outdoor exposure; coastal audits may require re-coating intervals.
Are custom sizes or finishes available for a Galvanized U‑Bolt?
Yes. Most suppliers offer custom inner diameters, leg heights, thread lengths, and finishes—including hot‑dip and PVC or zinc plating—on request.
Where can I order Galvanized U‑Bolt for bulk or tender projects?
You can source Galvanized U‑Bolts from certified fastener manufacturers in India offering ISO‑certified production, bulk‑order capacity, technical support and certified documentation.
