Steel Workshops & Warehouses
Portal frame and multi-storey steel buildings for factories, warehouses and logistics parks. This is the highest-volume line we export: workshops, warehouses and plant buildings shipped to Thailand, Indonesia, Cambodia and beyond, fabricated to the drawings supplied by the contractor or the plant owner’s engineer.

Where It Fits Best
01
Manufacturers building a plant in Southeast Asia
Fifteen of our thirty-two export projects are in Thailand alone — workshops, warehouses and plant buildings for electronics, food and industrial clients.
02
Buildings with heavy crane loads
Crane runway beams are where a cheap workshop building fails first. We fabricate heavy crane beams on our two heavy-structure lines.

Frequently asked about Steel Workshops & Warehouses
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.
Can you supply crane runway beams?
Yes. Heavy crane beams run on our two heavy-structure lines. Crane runways are where a cheaply fabricated building shows its problems first, so tell us the crane capacity and duty class along with the drawings.
We are a manufacturer building our own plant overseas. Have you done that before?
Frequently — it is the largest single pattern in our export record. Fifteen of our thirty-two export projects are in Thailand, and several clients have come back to us for plants in more than one country.
