Power & Industrial Plant Structures
Structural steel for power plants and process industries — boiler house framing, turbine hall structures, main plant buildings and ancillary structures. We have supplied fly-ash retrofit, biomass, coal-fired and nickel-alloy plant projects across Southeast Asia and South Asia, fabricated to the EPC contractor’s drawings.

Where It Fits Best
01
EPC contractors bidding EN-specified projects
When the tender specifies EN 1090 execution class, most Chinese fabricators are ruled out at prequalification. Our EXC3 certificate is issued by EUROCERT and can be verified directly with them.
02
Chinese manufacturers building plants overseas
We have supplied structures for Chinese industrial groups building in Cambodia, Indonesia and Turkey — the same client returning across three countries.
03
Power plant retrofits with tight structural tolerances
Fly-ash and boiler retrofit work has to fit existing plant. EXC3 covers the tolerance and traceability regime that kind of work needs.

Frequently Asked Questions
Do you work to our drawings, or do you design?
What happens to our drawings after we send them?
Can you meet an EN 1090 execution class requirement?
What are your welding qualifications?
What is your minimum order, and what are your lead times?
How is the steel packed and shipped?
Can you supply the mill certificates and inspection records?
Our tender is designed to EN standards but the plant is in Southeast Asia. Does your CE certificate still apply?

Frequently asked about Power & Industrial Plant Structures
Do you work to our drawings, or do you design?
We work to your drawings. Our EN 1090-2 certificate states "Design: Not include" — we are a make-to-print fabricator, so the engineering responsibility stays with your consultant or EPC contractor. Send us the shop drawings or the design drawings with a scope description and we will quote the fabrication.
What happens to our drawings after we send them?
They remain your property. We use them to quote and fabricate your job and we do not share them or reuse them on other projects. If your project requires a confidentiality agreement before you send anything, tell us and we will sign yours.
Can you meet an EN 1090 execution class requirement?
Yes, up to EXC3. Our certificate 1128-CPR-10.09.0686 is issued by EUROCERT S.A. in Greece under EN 1090-2:2018, covers execution class EXC3, and is valid until 13 March 2028 under annual surveillance. EXC3 covers bridges and other high-consequence structures; EXC1 and EXC2 are included below it. You can verify the certificate with EUROCERT directly.
What are your welding qualifications?
We hold ISO 3834-2:2021 (certificate 10.09.0687), the comprehensive tier of the welding quality standard, and our welding coordinator holds the International Welding Engineer (IWE) qualification per ISO 14731:2019 §6.2.2. Our welding procedure qualification records cover processes 135 (MAG), 136 (FCAW) and 135+121, material group 1.2, at plate thicknesses up to 30 mm.
What is your minimum order, and what are your lead times?
Both are confirmed per project rather than quoted as a blanket figure — our export projects have ranged from 5 tonnes to 2,000 tonnes, and lead time depends on tonnage, complexity and coating scope. Send the drawings and target dates and we will confirm both in writing before you commit.
How is the steel packed and shipped?
Sea freight, packed for container or breakbulk depending on member length and tonnage. We have shipped to 14 countries including Thailand, Indonesia, Cambodia, the Philippines, Egypt and Türkiye. Tell us the destination port and incoterms you need quoted.
Can you supply the mill certificates and inspection records?
Yes. Material traceability and inspection documentation are part of what the EXC3 execution class and ISO 3834-2 require, so the records exist as a matter of course. Tell us at enquiry stage what your consultant needs to see and in what format.
Our tender is designed to EN standards but the plant is in Southeast Asia. Does your CE certificate still apply?
The certificate is about how we execute the steelwork, not about where it ships. EN 1090-2 EXC3 is a statement that our factory production control and welding have been assessed and are audited annually by a European notified body. That is what a consultant checking your supplier chain wants to see, whichever country the plant is in.
Have you fabricated for power plant projects before?
Yes. Our export record includes a 2,000-tonne fly-ash retrofit in the Philippines, a 1x12MW coal-fired plant in Pakistan, two biomass power projects in Sri Lanka, and a nickel alloy plant in Indonesia. We can tell you the fabrication scope on any of these.
