Product Introduction
A weld stud is a fastener — headed, threaded, or plain-shank — that is fusion-welded to a base metal in a single arc discharge, using a stud welding gun instead of drilling and bolting. It creates a full-penetration joint in under a second, giving structural steel, sheet metal, and precast concrete a fixing point as strong as the parent material.
The part looks simple. What determines whether it welds clean or fails inspection is upstream: steel chemistry, flux-tip consistency, shank straightness, and dimensional tolerance. ZOC controls all four in-house, so every stud that leaves our line performs the same way on your gun, at your settings, on your site.

Selection Guide
Skip the guesswork. These are the four variables that actually determine which weld stud type, diameter, and grade fits your job.
Confirms whether drawn-arc or short-cycle welding is achievable without burn-through.
Shear, tension, or fatigue loading sets the diameter and grade you need.
Coastal, chemical, or high-humidity sites call for stainless or a plated finish.
Your gun's drawn-arc or CD capability narrows down which stud series will actually weld.

Industry Applications
From high-rise frames to offshore platforms, the same batch-controlled studs are qualified across these four sectors.
Optimized for welding high-strength shear connector studs on thick steel beams and metal deck flooring under heavy loads.
Delivers exceptional arc stability and deep penetration required for massive concrete-steel composite bridge decks and infrastructure.
Engineered with automatic grid voltage compensation to combat harsh shipyard power fluctuations, ensuring rust-proof, full-strength welds.
Perfect for dense, heat-resistant stud and anchor installation inside power plant boilers, industrial linings, and smelting furnaces.

Product Advantages
Factory-direct doesn’t just mean a better price — it means control over every variable that determines whether a stud welds clean the first time.
In-house cold heading and heat treatment mean tolerance and tensile strength are locked before the stud ever ships — not inspected after the fact by a trading middleman.
ISO 9001, AWS D1.1, EN ISO 13918, and CE certification, with every batch backed by a mill test report you can hand to your inspector.
Non-standard length, diameter, or thread specs are tooled to your drawing, so a project spec doesn't force you to redesign around a catalog part.
Standard items ship from stock; custom runs hold to a quoted production schedule, so your site sequencing doesn't stall on a supplier delay.
See how these advantages translate into your landed cost.
Manufacturing Process
Every stage is logged against the batch number, so any stud you receive can be traced back to its raw material heat and process settings.
Incoming wire rod checked for chemistry & diameter
Shank and head formed on multi-station formers
CNC thread rolling and shank turning to tolerance
Controlled hardening for target tensile strength
Zinc plating or galvanizing per spec
Counted, boxed, and batch-labeled for export

The Frequently Asked Questions (FAQ) section addresses key technical and commercial considerations for specifying and sourcing high-performance weld studs. Whether evaluating mechanical load requirements, international standard compliance (ISO 13918 / AWS D1.1), or process compatibility across Drawn Arc, CD, and Short Cycle welding systems, these answers provide clear, actionable insights to streamline procurement and ensure reliable structural connections.
Weld studs are specialized threaded or unthreaded metal fasteners designed to be fused directly onto a metal substrate using stud welding processes such as Drawn Arc, Capacitor Discharge (CD), or Short Cycle. Unlike traditional bolts, weld studs create a full-cross-section, permanent joint without requiring drilling, tapping, or access to the reverse side of the base material.
The main types of weld studs include Drawn Arc Weld Studs (ideal for heavy structural steel and thick plates), CD Weld Studs (designed for sheet metal and thin materials without backside marking), Short Cycle Weld Studs (suited for automated automotive and sheet fabrication), and Insulation Pins (used for securing thermal insulation materials).
Our weld studs are manufactured from high-quality carbon steel, stainless steel (AISI 304/316), and aluminum alloys. They can be reliably welded onto mild steel, structural steel, stainless steel, and galvanized sheet metal, depending on the chosen stud material and welding process.
Selecting the right weld studs depends on your base plate thickness, required load capacity, and welding equipment. As a general rule, Drawn Arc weld studs (Ø6mm to Ø25mm) are recommended for heavy load-bearing applications, while CD weld studs (M3 to M10) are preferred for light-duty sheet metal assembly.
Yes. All ZOC weld studs are manufactured in strict compliance with international standards, including ISO 13918 and AWS D1.1. Every batch undergoes rigorous quality control, including tensile strength testing, dimensional checks, and torque testing to ensure zero-defect performance on site.
To prevent corrosion and transport damage, our weld studs are packaged in moisture-proof plastic inner bags, packed into heavy-duty corrugated export cartons, and secured on fumigated wooden pallets. We support both FCL (Full Container Load) and LCL shipments with quick dispatch times.
