FAQ:

Q1. What does Loong's Arc manufacture?

A: Loong's Arc manufactures custom steel structure systems: portal frame (PEB) buildings, box columns and box beams, steel trusses, and cruciform columns, supplied with insulated sandwich panels, standing-seam roofing and side cladding. The factory has operated since 1994 and ships from Dalian Port to industrial, logistics and commercial projects worldwide.

Q2. Which design codes can you fabricate to?

A: Structures are engineered and detailed to AISC and AISI (United States), CSA (Canada), EN 1993 Eurocodes (Europe) and GB (China). Tell us the destination country at enquiry stage and the frame is detailed to that market's code from the first drawing, so no re-detailing is needed after award.

Q3. Which certifications does the factory hold?

A: The quality system is certified to ISO 9001, and welding is executed to ISO 3834, CE EN 1090 (execution class EXC3), CWB / CSA W47.1 for Canada and AWS D1.1 for the United States. Each project ships with material traceability records and inspection reports covering every weld.

Q4. What is the largest clear span you can supply?

A: Standard portal frames provide clear spans of 18 to 36 metres without internal columns. Spans of 60 metres and above are achievable with specialized design, such as truss or arch systems. Beyond roughly 36 metres the governing constraint shifts from steel cost to transport: check container or breakbulk limits before fixing the span.

Q5. How are structures shipped and who handles installation?

A: Structures ship from Dalian Port under FOB, CIF, DAP or DDP terms — you choose how much of the chain we manage. Site assembly is fully bolted with pre-punched holes, so erection requires no site welding; local crews can erect from our drawings.
