Core Business of STP&I can be categorised into three key groups:

  1. Engineering Service: The Company provides engineering service in detail design of steel-to-steel connection, shop drawing for steel structure, piping, and erection works by various specialized software.

  2. Fabrication: The Companyprovides fabrication service and has the capability to fabricate steel and pipe in workshop which equipped with state of the art machine and equipment, CNC Cutting and Welding machine, Press machine, automatic Blasting machine and other tools necessary to undertake the variety and complexity of fabricated products to ensure the efficiency of fabrication processes and cost effective.

  3. Construction: STP&I's construction works include assembly, mechanical equipment installation and erection for various manufacturing plants. The Company performs the works both at the Company’s facilities and at the client’s project site.

Company Products can be categorized into 4 groups.:

  1. Steel Structure Fabrication
    1. Steel structures for heavy industrial such as gas separation plant, power plant, refinery, petrochemical plant, etc.
    2. Steel Structure for building such as high – rise building, airport terminal.
    3. Steel Structure for infrastructure system such as bridge,elevated road, airport, etc.
  2. Piping Fabrication: STP&I has expertise in piping fabrication which includes piping pre-fabrication, piping erection, and pipeline constructions. The spoon fabrication is carried out in STP&I’s facilities, then the semi - completed products are transported to the project sites for installation.
