High-Grade Steel Selection at Alura Trailer
Built Strong with ST52, Domex, and Hardox Steels
Why Steel Grade Matters in Trailer Manufacturing
In the world of semi-trailer production, material quality plays a critical role in safety, load capacity, and overall durability. At Alura Trailer, we rely on premium-grade steels like ST52, Domex, and Hardox to build trailers that can handle the world’s toughest transport demands— from construction sites to mining zones.
ST52: Strong, Versatile, Cost-Efficient
ST52 steel is known for its high strength and excellent weldability. It’s a structural steel that balances strength and flexibility, making it ideal for the chassis of flatbed trailers, tipper trailers, and lowbeds.
Its structural integrity ensures long-term resistance to mechanical wear and vibrations during heavy-duty use. In addition, it supports precise laser cutting and CNC machining, crucial for our precision engineering process.
Domex (Strenx): Lightweight with High Yield Strength
Domex, now branded globally as Strenx, is a hot-rolled advanced high-strength steel (AHSS) known for its exceptional strength-to-weight ratio. Used in our specialized trailers, Domex enables:
- Reduced tare weight
- Increased payload capacity
- Better fuel efficiency
Domex is especially beneficial in mobile workshop trucks where weight optimization is critical for mobility and equipment load-out.
Hardox: Unmatched Wear Resistance
Hardox is one of the toughest wear plates available in the industry. Known for its abrasion resistance and extreme impact strength, we use Hardox in:
- Tipper trailer bodies
- Fuel tanker skins exposed to debris or stone impacts
- Heavy-duty mining transport trailers
Its long lifespan and reduced need for maintenance make it a smart investment for clients operating in high-impact environments.
Trailer Design Meets Steel Expertise
Our team at Alura Trailer doesn't just select steel randomly—we match the grade to the purpose of your trailer. From ST52 for base frames, to Domex for weight-sensitive builds, and Hardox for aggressive terrains, each metal is used where it performs best.
