Looking for a building material that's strong, affordable, and built to last? Primegold Steel Slag Blocks are engineered for modern construction needs. Made from recycled steel slag, cement, and fly ash, these blocks deliver exceptional performance at just ₹28 per unit.

Perfect for coastal construction, industrial facilities, and budget-conscious projects, our steel slag blocks resist saltwater corrosion and offer the lowest cost per wall area in the market.

What are Steel Slag Blocks?

Steel slag blocks are a type of high-performance building block produced by combining recycled steel slag, a byproduct of steel manufacturing, with cement and fly ash. Manufactured through a controlled compression process, steel slag blocks do not rely on mining topsoil or kiln firing like traditional clay bricks.

This unique composition makes the blocks denser, stronger, and more uniform compared to conventional bricks. The blocks are 400×200×150 mm in size, with a weight of 17-18 kg, and have a smooth finish that requires minimal plastering.

What makes them stand out? Steel slag blocks naturally resist saltwater corrosion, chemical exposure, and environmental degradation. They are 100% eco-friendly, turn industrial waste into a superior building material, and offer the lowest cost per wall area in the market.

How Primegold Manufactures Steel Slag Blocks

Our manufacturing process ensures consistent quality:

Raw Material Selection – Premium steel slag, cement, and fly ash
Precise Mixing – Automated systems for exact proportions
High-Pressure Molding – Hydraulic compression for uniform blocks
Controlled Curing – Proper strength development during the curing process
Quality Testing – Every batch is tested for strength, absorption, and chemical resistance

Benefits of Using Steel Slag Blocks?

Steel slag blocks are manufactured using steel industry waste, making them 100% eco-friendly. The combination of steel slag, cement, and fly ash creates blocks that are:

Profile Types:

Saltwater & Corrosion Resistant – Perfect for coastal areas where regular bricks deteriorate quickly
Cost-Effective – At ₹28 per unit, they offer the best value for money
Load-Bearing – Suitable for structural walls in multi-story buildings
Low Water Absorption – Less than 10%, preventing dampness and mold
Heat Resistant – Keeps buildings comfortable year-round
Smooth Finish – Requires minimal plastering, saving time and money

Technical Specifications:

Size: 400×200×150 mm
Weight: 17-18 kg per block
Compressive Strength: 7-9 N/mm²
