ATAD STEEL STRUCTURE CORPORATION

Manufacturing

With a well-trained workforce of over 1,000 professional staffs, quality management system ISO 9001:2008, ISO 14001:2004, OHSAS 18001:2007 and a 176,000 m2 factory, 11,000 MT/month for steel structure, 600 MT/month for cold-formed member and 200,000 m2/month for steel panel with high technology automatic production facilities, ATAD delivers optimal solution, high-quality products and perfect services for your project.

Manufacturing process has three separate stages to manufacture three main constituting components including:

Primary members: column, beam
Secondary members: purlin, door…
Sheets: roof sheet, wall cladding, flashing…

A. Primary member

1. Cutting:

  • By the CNC automatic multi-head cutting machine, steel plates can be cut to any shape design. All the plates are cut to any required size by extremely hot temperature with thickness up to 80mm.
  • Equipment and machines:
    + CNC automatic cutting machine.

2. Hole Punching

  • After cutting, use the automatic laminating machine to drill or punch holes on the cutter plates as required.
  • Equipment and machines: drilling machine, hole-punching machines (03 units).

4. Welding and connection details welding:

  • After assembling, components are transferred to the next procedure of welding two flanges of steel plates with submerged arc weld. This process creates welds with high quality, big intension and absolute sealing.
  • ATAD weld completely by alternating electrical poles welding. All kinds of welds are done in accordance with the latest publish of Vietnamese Technique Manual Book’s standards and instructions.
  • Equipment and machines: automatic welding machines (10 units), hand welding machines (100 units).

5. Surface cleaning:

  • Built-up steel plates and welds are then cleaned physically or cleaned by using the sand-spraying machine, depending on the customers’ choices.
  • Equipment and machines: automatic shot-blasting machine, grinders (10 units).

6. Painting:

  • ATAD uses the industrial high-pressure painting machine according to American technology. Building components will be sprayed of grey paint coating or red paint coating or other special paints according to the customers’ choices.
  • Equipment and machines: High-pressure paint spraying machine, grinders (5 units)

B. Secondary members

1. Forming

  • All secondary components such as purlins and girts are manufactured from the Zinc-coated Cold-Rolled Steel Sheet in Coils or black-coated Cold-Rolled Steel Sheet in Coils in accordance with ASTM standard. These components are then cold-formed into “Z” or “C” shape with the thickness from 1,5mm to 2,5mm.
  • The time during adjusting rollers is around 2 ~ 3 minutes without changing rollers. After the roll is formed by this roll forming machine, the surface will be very smooth and beautiful without any scratch on the surface.
  • Machine: Purlin Rolling Machine

2. Hole punching

  • Purlins and girts can be supplied plain, or punched using hole punching standard, spaced to your specifications.

3. Painting

  • ATAD uses the industrial high-pressure painting machine according to American technology. Building components will be sprayed of grey paint coating or red paint coating or other special paints according to the customers’ choices.

C. Panels

  • All kinds of steel panels are rolled from the high-quality steel, zincalume-coated cold-rolled steel with undercoat painting conforming to ASTM.
  • Machine: Purlin Rolling Machine.
