How to Create the Perfect Jointless Floor Reinforced with Lanmix Steel Fiber

How to Create the Perfect Jointless Floor Reinforced with Lanmix Steel Fiber

In modern industrial and commercial construction, the demand for flat, durable, crack-free concrete floors without joints is rapidly increasing. Traditional concrete flooring typically requires expansion joints to manage shrinkage and cracking, which leads to higher maintenance costs and compromises visual aesthetics. To address this issue, jointless floors reinforced with Lanmix Steel Fiber have emerged as a breakthrough solution, now widely adopted in major projects across the globe.

Understanding Jointless Concrete Floors

A jointless floor refers to a large-area concrete slab that is cast monolithically, without the need for saw-cut joints, thanks to its internal crack control capability. By incorporating Lanmix dispersed steel fibers directly into the concrete mix, millions of tiny, high-strength fibers form a 3D network throughout the slab. This provides:

• Enhanced tensile strength and shrinkage crack resistance

• Uniform stress distribution across the entire floor

• Reduced risk of large cracks and edge failures, even under heavy loads

• Improved long-term durability and lower maintenance costs

Lanmix Steel Fiber – A Trusted Reinforcement Choice

With years of research and development, Lanmix offers the UF075-6080NP steel fiber, engineered specifically for industrial and high-load logistics floors. This hook-end steel fiber features a tensile strength ≥1200 MPa, delivering excellent anchorage within the concrete matrix.

Common dosage ranges from 20 to 35 kg/m³, depending on load demands and usage functions. The double-hook design of the fiber not only enhances its bond with concrete but also minimizes the risk of "balling" during the mixing process, ensuring even fiber distribution.

Proven Success in Large-Scale Applications

Projects such as the Thailand Double Coin Tire factory (100,000 m²) and the Malaysia Continental Tire warehouse (200,000 m²) clearly demonstrate the superior performance of Lanmix steel fiber in jointless floor construction. After completion, the floors showed an ultra-flat surface with no visible cracking, exceeding the high-performance standards required in modern industrial settings.

The Flooring Solution of the Future

Choosing jointless concrete floors is not just a technical decision—it's an investment in efficiency and longevity. This solution helps reduce construction time, labor costs, and long-term maintenance, while ensuring structural integrity. Particularly in automated facilities where forklifts and robots operate continuously, eliminating joints significantly reduces equipment wear and improves operational safety.
