World Steel · Comprehensive fire protection solutions
World Steel delivers integrated fire protection for commercial and industrial steel buildings – combining structural steel expertise with carefully selected fire protection products and systems, tailored to project-specific fire resistance requirements, applicable international standards and local building regulations, and supported by the technical documentation and certification of the products chosen.
In a building fire, gas temperatures follow the standard fire curve (ISO 834 / ASTM E119 / AS 1530.4) and pass 800 °C within about 20 minutes. Unprotected steel heats up quickly; at around 600 °C its yield strength has fallen to about half. When it reaches its critical temperature – typically 500–620 °C, depending on how heavily the member is loaded – the member can no longer carry its load.
Passive fire protection insulates the steel so it stays below that temperature for the period the building code requires. The amount of protection depends on the member's section factor (Hp/A in Europe, ksm in AS 4100, W/D in the USA): thin, light sections heat faster and need more protection than heavy ones.
Solutions by building type
Building use, fire load and occupancy decide the ratings and the systems – World Steel matches both to the steel structure.
01People-intensive buildings with escape routes, atriums and visible steel – appearance, insulation (I) criteria and smoke control matter. Typical: intumescent coatings on exposed steel, boards or sprays on concealed steel, fire-rated doors, glazing and curtains.
02Large spans and high fire loads – compartmentation, insurer requirements and robust protection. Typical: sprays or boards on frames, stone wool sandwich panels, fire walls with shutters, firestop at services; hydrocarbon systems where process fires are possible.
03Steel close to processes and equipment – exposure, impact and hydrocarbon scenarios. Typical: epoxy intumescents (UL 1709 / EN 1363-2), high-density sprays and exterior-grade systems with ISO 12944 corrosion protection.

Steel + fire protection in one package
For export projects, applying the intumescent coating in the factory saves weeks on site. World Steel blasts, primes and coats members in its painting shop to the fire engineer's thickness schedule, records the dry film thickness member by member and packs the steel to protect the finish. Boards, sprays and fire stopping are supplied with the structure and the envelope. See also our stone wool range and fire-rated gypsum board.
International fire protection compliance
World Steel provides comprehensive fire protection solutions for commercial and industrial steel buildings, with products and systems selected to meet project-specific fire resistance requirements, applicable international standards and local building regulations.
Standards fall into distinct roles: design standards (EN 1993-1-2, AS 4100 Section 12, AISC 360 Appendix 4) size the protection; test standards (ISO 834, ASTM E119, EN 1363–1366, AS 1530.4) produce the evidence; classification standards (EN 13501) express the result; execution and inspection standards (AS/NZS 5131, EN 1090-2, ASTM E605) govern application and checks; certifications and listings belong to specific products and systems – and are confirmed for each market, never assumed.

FAQ
Steel does not melt in a building fire, but it loses strength. Its critical temperature – typically 500 to 620 °C – depends on how heavily it is loaded; at about 600 °C it keeps roughly half its room-temperature yield strength.
The heated perimeter divided by the cross-section area. A high section factor means a thin, light member that heats quickly and needs thicker protection.
Coatings are slim and keep the steel visible – ideal for exposed steel and shop application up to about 120 minutes. Boards are dry, robust and reach longer ratings. Many projects combine both.
Yes – intumescent coatings can be applied in our painting shop to the fire engineer's schedule, with dry film thickness records for every member.
It is set by the building code of your country, the building use, height and compartment size. Your fire engineer or authority confirms it; we design the protection to suit.
No – fire certifications belong to specific products and tested systems from their manufacturers. World Steel selects products whose certification or test evidence is valid in your market and supplies those documents. World Steel’s own certifications cover steel fabrication (AS/NZS 5131 CC3, EN 1090 EXC3, ISO 3834-2, IAS AC472).
No. Non-combustibility describes how a material reacts to fire; a fire resistance rating belongs to a tested element or system with its thickness, joints, fixings and supports.
Project location and building type, the fire strategy or required ratings, applicable standards, steel drawings or tonnage, the estimated protection area and any specification – our fire protection form collects all of it and accepts drawings.
Submit your project requirements – ratings, standards, drawings and protection areas – and our engineering team proposes a project-specific fire protection solution with the steel package.
