UTM SCAFFOLDING: Premium Scaffolding Couplers – Safety & Durability Redefined
Welcome to UTM SCAFFOLDING, your trusted partner for high-performance scaffolding solutions. With years of expertise in the scaffolding industry, we are committed to delivering top-tier products that prioritize safety, durability, and operational efficiency. Our scaffolding couplers are engineered to meet the rigorous demands of construction sites worldwide, providing reliable connections that form the backbone of stable scaffolding structures.

Why Choose UTM Scaffolding Couplers?

  • Our scaffolding couplers are forged from high-grade Q235 steel, a material renowned for its exceptional strength and toughness. Each coupler undergoes a rigorous hot-dip galvanization process, which creates a corrosion-resistant layer that withstands harsh environmental conditions—from heavy rain and humidity to extreme temperatures. This treatment ensures that our couplers maintain their structural integrity even after years of heavy use, reducing replacement costs and minimizing downtime.

    Superior Material Selection for Maximum Durability
  • Safety is non-negotiable at UTM SCAFFOLDING. Our couplers are designed with precision to ensure a tight, secure grip on scaffolding tubes. The clamping mechanism features a high-torque bolt and nut system that provides uniform pressure, preventing slippage and ensuring a stable connection. Each product undergoes strict quality control tests, including load-bearing tests and fatigue tests, to ensure compliance with international standards such as EN 74 and AS1576. You can trust our couplers to support heavy loads and protect workers at height.

    Precision Engineering for Unmatched Safety
  • We offer a comprehensive range of scaffolding couplers to meet the diverse needs of construction projects. Our product line includes:
    - Right-Angle Couplers: Ideal for connecting scaffolding tubes at 90-degree angles, perfect for forming the vertical and horizontal frames of scaffolding structures.
    - Swivel Couplers: Designed to connect tubes at any angle, providing flexibility for complex scaffolding configurations, such as curved or sloped structures.
    - Putlog Couplers: Used to attach putlogs or transoms to the main scaffolding frame, ensuring secure support for working platforms.
    - Sleeve Couplers: For joining two scaffolding tubes end-to-end, extending the length of tubes to fit project requirements.

Different Production Processes
According to different production processes, there are mainly the following two types:
Forged scaffolding couplers
Pressed scaffolding couplers
forged coupler
Forged coupler raw material Q235 raw steel, process forging, surface plating white zinc treatment.
Scaffold forged coupler is a kind of scaffold connecting parts, forged coupler has high strength and hardness

The characteristics of the scaffolding forging couplers
 are as follows:

The connection between the forging coupler and the main beam and the auxiliary beam of the scaffold is fixed by the hook and the locking device, which is suitable for the large-span engineering construction.
The forging coupler is easy to assemble, easy to disassemble, and can be used many times, which reduces the construction cost and improves the operation rate.

pressed coupler
Pressed coupler raw material Q235 plate, process pressed, surface plating color zinc treatment.

Compared to forged couplers, pressed couplers have a price advantage and can particularly address the production shortcomings that cannot be overcome by forging processes. Using Q235, Q355, SPHC, and other grades of steel plates, these couplers are processed into couplers that meet the requirements of BS EN74-1:2005 through processes including cutting, mold forming, galvanizing, and assembly. Compared to forged couplers, pressed couplers have a certain cost advantage and also address the production gap that cannot be achieved using some forging techniques.
