Does Joint Star Steel supply international buyers?

Yes. Since 2010 our scope has covered both the local market and export markets. We supply designed and fabricated steel structures, sandwich panels and allied building materials, with drawings, marked members and packing lists so that erection on site is straightforward.

Which sandwich panel core should I choose: EPS, PU or rock wool?

EPS is the most economical and lightweight option for general roofing, walls and site offices. PU (polyurethane) offers the best thermal insulation per thickness and suits cold rooms and temperature-controlled warehouses. Rock wool is non-combustible and is preferred where fire resistance and acoustic performance are priorities.

What information is needed to start a pre-engineered steel building design?

Share the building use, length, width and eave height, site location, crane or mezzanine requirements, roof and wall cladding preference and any local code requirements. Our engineers use this to prepare a structural concept and technical proposal.

Can you deliver a complete turnkey package including civil work?

Yes. We offer full packages that combine steel building design, fabrication and erection with civil and RCC construction such as foundations, floor slabs and supporting structures.

How much experience does Joint Star Steel have?

Joint Star Steel Structure Ltd. has operated since 2010, has completed more than 352 projects for over 120 clients and employs a team of 100+ engineers, fabricators and erection specialists.
