Steel Coating in Saudi | Steel Coating Supplier in Jeddah, Saudi

Nassguard offers Steel Coating in Saudi with SC604 Intumescent Steel Coating, a solvent-based system for the passive fire protection of structural steelwork. Designed for off-site application, SC604 allows fabricators to incorporate fire protection into the workshop coating process before steel members reach the construction site.

The product is optimised for 60-minute fire resistance, with limited 90-minute protection available for suitable configurations. The required coating thickness depends on the steel section, its exposure and the project’s fire-engineering requirements.

What Is SC604 Intumescent Steel Coating?

SC604 is a single-pack, acrylic thin-film intumescent coating for internal and semi-exposed structural steelwork. Under fire exposure, an intumescent coating expands to form an insulating layer. This layer slows heat transfer to the steel and helps delay the temperature rise that reduces its load-bearing strength.

SC604 forms part of a specified coating system. The primer, intumescent layer and any required topcoat must work together. Selecting the correct combination matters as much as choosing the fire-protection coating itself.

Key Features of SC604 Steel Coating

SC604 combines a thin-film finish with features suited to planned fabrication and coating work.

• Off-site application: Supports workshop coating before delivery and erection.
• Single-pack formulation: Simplifies preparation without mixing separate reactive components.
• 60-minute optimisation: Provides a practical option for suitable one-hour fire-protection requirements.
• Limited 90-minute capability: Covers additional applications within the assessed scope.
• Borate-free composition: Uses a borate-free intumescent formulation.
• High-solids formulation: Supports the required protective film build.
• Compatible coating systems: Works with selected primers and topcoats.
• Optifire®+ identification: Provides a traceability feature for the applied product. Nullifire UK

Applications of Steel Coating in Saudi

SC604 intumescent steel coating suits projects where structural members require a specified period of fire resistance and off-site application fits the construction programme.

Its assessed applications include suitable:

• I-section beams and columns used in structural frameworks.
• Hollow-section beams and columns within the applicable assessment limits.
• Cellular beams requiring a section-specific fire-protection design.
• Concrete-filled hollow sections covered by the relevant loading information.
• Solid steel tension rods requiring reactive fire protection.
• Steel, cast iron and galvanised steel surfaces, with appropriate preparation and compatible coating systems.

Nassguard supports enquiries across Riyadh, Dammam, Jubail, Jeddah and Al Khobar. For each location, the specification should account for the actual exposure conditions, construction sequence and required fire rating.

Certifications, Standards and Compliance

• ETA 21/0683 — European Technical Assessment: Covers SC604 as a reactive coating for the fire protection of steel elements.
• CE Marking and Declaration of Performance — SC604-20220107: Declares performance under AVCP System 1, referencing 2812-CPR-GA5051.
• EN 13381-8 — Reactive Protection Applied to Steel Members: Identifies the fire-test assessment method referenced in SC604’s declaration.
• EAD 350402-00-1106 — Reactive Coatings for Steel Fire Protection: Provides the assessment basis for SC604’s European Technical Assessment.

Steel Preparation and Coating Application

Plan the coating process alongside fabrication, transport and erection. This helps teams identify inspection stages and prevent damage after application.

• Confirm the fire design: Record the required resistance period, steel sections and design temperatures.
• Prepare a thickness schedule: Assign the required intumescent thickness to each member.
• Prepare the steel: Remove contamination and achieve the surface condition required by the selected system.
• Check primer compatibility: Verify the primer type, condition and thickness before overcoating.
• Control application conditions: Monitor temperature, humidity, ventilation and condensation risk.
• Measure the coating: Use wet-film checks during application and dry-film measurements after drying.
• Apply the specified finish: Use a compatible topcoat where the exposure or finish requirement calls for one.
• Plan handling: Allow appropriate drying before lifting, stacking or transporting coated members.

For Saudi projects, workshop heat, direct sunlight and delivery conditions deserve attention when setting the application and handling programme.

Inspection and Maintenance

Inspection should continue beyond the coating workshop. Transport, erection and later building work can damage an otherwise satisfactory finish.

• Check before dispatch: Record coating condition and thickness measurements.
• Inspect after erection: Look for scraping, impact damage and exposed steel.
• Review connection areas: Check locations affected by bolting, welding or site modifications.
• Investigate coating defects: Assess cracking, lifting or moisture-related damage before repair.
• Restore the complete system: Reinstate the specified primer, intumescent layer and finish where necessary.
• Keep traceable records: Retain batch details, member references, measurements and repair information.

Frequently Asked Questions

1. What is SC604 used for?
SC604 provides intumescent fire protection for suitable structural steel members.

2. Is SC604 designed for off-site application?
Yes. It is the off-site, solvent-based grade, suited to workshop coating before delivery.

3. Does every SC604 application provide 90-minute protection?
No. SC604 is optimised for 60 minutes. Its limited 90-minute applications require a suitable assessed configuration.

4. What thickness should the coating have?
The required dry-film thickness depends on the steel section, section factor, fire exposure and design temperature.

5. Can SC604 be applied over any primer?
Use a compatible primer system. Primer identity, condition and thickness need checking before application.

6. Is a topcoat always necessary?
The requirement depends on the specified coating system, exposure conditions and finish. Confirm it during product selection.

7. What information should accompany a quotation request?
Provide the steel schedule, surface area, required fire rating, thickness schedule, coating-system details and delivery location.

Conclusion

SC604 Intumescent Steel Coating gives fabricators an off-site option for protecting suitable structural steelwork against fire. Its single-pack formulation, thin-film technology and assessed performance support a planned workshop coating process.
