Generation of shop fabrication drawings in Tekla Structures, piece-marked part lists, bolt schedules, and anchor setting plans for client sign-off.

Step 03

Automated Production

High-precision plate cutting, automatic submerged-arc beam welding, continuous sandwich panel line processing, and multi-layer corrosion protection coating.

Step 04

Dispatch & Site Support

Bundle wrapping with seaworthy packaging, container optimization, and on-site deployment of experienced technical supervisors for flawless assembly.

Procurement FAQs

Frequently Asked Questions

In-depth responses for procurement directors, structural engineers, and commercial project managers.

What international structural engineering standards do your designs adhere to?

Our engineering design wing utilizes licensed Tekla Structures, STAAD Pro, and AutoCAD, strictly conforming to AISC (American Institute of Steel Construction), MBMA, AWS D1.1 structural welding code, and BNBC standards to ensure seamless international compliance across heavy industrial, warehouse, and commercial spans.

How does Joint Star Steel handle quality control for structural fabrication and export orders?

Every steel component undergoes standardized QA/QC protocols: ultrasonic non-destructive testing (NDT), shot-blasting to Sa 2.5 cleanliness, automated submerged arc welding inspection, dry film thickness (DFT) paint verification, and piece-marking before containerization. Mill Test Certificates (MTC) accompany every shipment batch.

Can you provide overseas on-site installation guidance or turnkey EPC delivery?

Yes. We offer turnkey execution locally and deploy experienced project managers, erection engineers, and site supervisors for overseas industrial buyers alongside comprehensive 3D erection drawings and piece-matched packing lists to ensure safe, rapid assembly by local erectors.

What are the thermal and energy-saving advantages of your sandwich panel cladding systems?

Our in-house produced EPS, Polyurethane (PU/PIR), and Rock Wool panels provide optimal U-values, eliminating thermal bridging and lowering HVAC operational electricity costs by up to 35% in tropical and demanding industrial warehouse environments while providing exceptional sound dampening and moisture barriers.
