Specification Scaffolding pipe Outside diameter 48.3MM(1 1/2 INCH) Wall thickness 3.2MM/4MM Length 1-12M, normally 6M, also depends on the requirements Zinc coating thickness normally 40 micron (280g/m²), also depends on the requirements Surface treatment Engrave, embossing, cutting Anti corrosion coating Galvanizing Chemical Composition SS400 SS500 STK 490 STK 500 Carbon (C) ≤ 0.25% ≤ 0.25% ≤ 0.20% ≤ 0.23% Silicon (Si) ≤ 0.50% ≤ 0.55% ≤ 0.35% ≤ 0.35% Manganese (Mn) No specific limit No specific limit ≤ 1.50% ≤ 1.50% Phosphorus (P) ≤ 0.050% ≤ 0.040% ≤ 0.040% ≤ 0.040% Sulfur (S) ≤ 0.050% ≤ 0.040% ≤ 0.040% ≤ 0.040% Processing process:
Raw Material Preparation (Steel Coil) → Slitting (Cutting to Width) → Forming (Roll Forming) →Welding (ERW or Furnace Welding) →Weld Seam Processing (Normalizing, Grinding) → Sizing and Straightening → Cutting to Length → Surface Treatment (Galvanizing, Coating) → Inspection and Testing → Marking and Packaging
Advantages:
1. High Strength and Durability
JIS G3444 pipes are made from carbon steel, which provides excellent mechanical strength. This makes them suitable for heavy loads in scaffolding systems, ensuring safety and stability.
2. Corrosion Resistance
These pipes are often coated (e.g., with zinc) to provide corrosion resistance, making them suitable for outdoor use, even in harsh weather conditions.
3. Uniform Wall Thickness
The standard ensures a consistent wall thickness, contributing to the uniform strength of the pipes, which is important for structural integrity and load-bearing capacity.
4. Versatility
The pipes come in various sizes and can be used for different scaffolding structures, including frames, braces, and towers, making them versatile in construction applications.
5. Cost-Effective
JIS G3444 pipes offer good quality at a reasonable price, making them a cost-effective option for temporary scaffolding systems in construction projects.
6. Ease of Fabrication and Installation
These pipes are easy to cut, weld, and assemble, allowing for faster construction and dismantling of scaffolding systems.
Application:
1. Scaffolding system
Temporary Frames: JIS G3444 Pipes are widely used in construction to create temporary frames to support workers, materials and tools at different heights.
Support Structures: They are used in scaffolding systems as vertical, horizontal and diagonal supports to ensure stability and safety during construction, repair or maintenance work.
2. House construction projects
Building Framing: These pipes are used as part of structural frames for temporary or permanent installations in residential, commercial, and industrial construction projects.
3. Infrastructure and Civil Engineering
Bridges and Roads: In infrastructure projects, these pipes are used as part of scaffolding and support systems during the construction or repair of bridges, roads, tunnels and other civil works.4. Shipbuilding and offshore platforms
These pipes are also used in scaffolding systems for shipbuilding, offshore oil platforms and other marine applications where corrosion resistance and structural integrity are critical.
5.Industrial maintenance and repair
JIS G3444 pipes are used for maintenance and repair of industrial facilities such as refineries, power plants and factories. They provide access to elevated areas for workers performing inspection or repair work.
6. Events and temporary structures
Stage and event settings: Due to their strength and ease of assembly, these pipes are also used to build temporary stages, seating and structures for events, concerts, exhibitions and sporting events.
