It incorporates BlueScope’s proprietary AZ100 coating technology, delivering superior corrosion resistance, long-lasting colour performance, and reliable durability — making it a smart and affordable choice for residential and light commercial buildings.
Why Choose PRIMAMAJU®?
01
BlueScope Expertise Backed
With over 130 years of steel manufacturing heritage, BlueScope products are developed and tested under extreme outdoor conditions during R&D stages.
Manufactured in accordance with ISO 9001 and ISO 14001 standards, PRIMAMAJU® steel reflects BlueScope’s commitment to consistent quality and performance.
02
BlueScope Material Warranty
PRIMAMAJU® steel is backed by BlueScope material warranty:
- Up to 15 years against perforation by corrosion
- Up to 5 years against excessive colour fading
03
4 Times More Durable
PRIMAMAJU® steel features an AZ100 aluminium-zinc alloy coating composed of 55% Aluminium, 43.5% Zinc, and 1.5% Silicon.
This advanced coating provides up to 4 times longer corrosion resistance compared to conventional galvanised steel (GI), ensuring a longer service life for your roof.
04
Extensive Colour Durability
PRIMAMAJU® steel incorporates advanced primer technology and a specially formulated top coat, delivering enhanced colour durability and long-lasting appearance beyond generic alternatives.
05
Thicknesses
Builders often refer to Total Coated Thickness (TCT), but it doesn’t always reflect the steel’s true strength. BlueScope defines thickness using After Painted Thickness (APT) and labels PRIMAMAJU® steel with Base Metal Thickness (BMT), ensuring customers get the right strength. Transparency in specifications means safety and integrity come first.
06
Wide Range of Colours
PRIMAMAJU® is available in a variety of practical and aesthetic colour options, including: Prima Awana, Prima Lada, Prima Cendana, Prima Hijau, Prima Biru, and more — allowing flexibility to match different architectural styles.
07
Eco-Friendly Coated Steel
PRIMAMAJU® steel is SIRIM ECO-LABEL certified by SIRIM QAS International (GEN member), ensuring environmentally responsible manufacturing with reliable performance.

To improve heat insulation and sound resistance for residential properties,
the fabricator applies Polyurethane Foam to the steel roofing.
Polyurethane Foam Steel Roofing
The roofing is now upgraded with high-performance polyurethane foam insulation, delivering exceptional comfort and durability for your home or workspace.
Key Benefits:
1. Heat & Sound Insulation
High closed-cell content (>90%) effectively blocks heat transfer and reduces noise.
One inch of rigid foam can block at least 70% of heat, improving indoor comfort.
2. Compressive Strength
The strong closed-cell structure provides superior load-bearing capacity and long-term durability.
Reinforced cell walls give the foam its high mechanical strength.
3. Water Absorption
Closed-cell foam does not absorb water, helping to prevent leakage and moisture-related issues.
4. Lifespan
Rigid foam offers stable insulation performance with a service life of over 20 years.
Polyurethane Foam Thickness Options:
- 20mm – Effective thermal and sound insulation
- 50mm – Superior insulation for maximum comfort and performance
By integrating Polyurethane Foam insulation, the metal roof not only reduces heat from the sun and minimizes rain noise but also enhances energy efficiency, indoor comfort, and a quieter environment.
