China 12"-24" Laser Welded Road Sawing Blade for Asphalt & Green Concrete Supplier, Factories
Product Description
Product Introduction
Engineered for the most demanding job sites, our laser welded diamond saw blades provide the ultimate solution for heavy-duty road sawing. Whether you need to cut asphalt with angle grinder setups for precision utility work or operate a high-powered walk behind asphalt saw for highway construction, these blades deliver unmatched structural integrity. Every asphalt saw blade in our lineup is manufactured with 100% laser-welding technology, ensuring the segments endure high-temperature stress without failure, significantly improving both cutting precision and operator safety.
This professional-grade Road Sawing Blade is specifically optimized for abrasive environments. Featuring a strategic U-slot and drop protection segment design, the blade effectively shields the steel core from the "undercutting" effect caused by abrasive slurry. It is the ideal choice for tackling asphalt concrete, asphalt over concrete, and green concrete with high efficiency. Our concrete saw blades are built using premium diamond grit and a specialized metal powder matrix, resulting in a sharp, long-lasting cutting edge that reduces the need for frequent wheel changes—saving you both time and money.
Designed for maximum versatility in the field, these blades are suitable for wet and dry cutting across a wide range of applications, including highways, driveways, parking lots, and general pavement maintenance. They are perfectly compatible with hydraulic gasoline saws and walk-behind asphalt saw equipment (up to 20HP). With various quality grades available, we provide the strength and durability required for professional road work and large-scale building projects, ensuring every cut is fast, clean, and cost-effective.
Features
Engineered with high-grade diamond grit and a specialized metal powder matrix, ensuring a sharp, aggressive cut while significantly extending the blade's service life.
Optimized diamond particle concentration in the rim provides consistent cutting performance, reducing friction and maximizing the return on investment for large-scale projects.
Features a strategic U-slot segment design combined with drop protection teeth. This specialized geometry shields the steel core from abrasive slurry, preventing premature failure during asphalt and green concrete cutting.
Equipped with a reinforced steel core and 100% laser-welded segments. This industrial-strength bond ensures the blade endures extreme stress and high temperatures without segment loss.
The Quick-Cut technology allows for faster feed rates and fewer wheel changes, directly translating into significant time and labor savings on the job site.
Optimized for professional equipment, including hand-held gas saws and walk-behind saws (rated up to 20HP). Ideal for both wet and dry applications.

Frequently Asked Questions (FAQ)
This blade is specially engineered for abrasive materials including asphalt, asphalt concrete, asphalt over concrete, and green concrete, while delivering reliable performance on cured concrete as well.
Yes, our diamond blades are versatile and fully compatible with both wet and dry cutting methods. Wet cutting will further prolong segment life and reduce operational airborne dust.
These blades are compatible with hand-held gas saws, angle grinder setups for utility cutting, and walk-behind saws rated up to 20HP.
The deeper drop segments and U-slot design help clear abrasive slurry rapidly and shield the steel core from abrasion, preventing segment breakage and premature core wear.
100% laser welding creates an exceptionally strong metallurgical bond between the diamond segment and the steel core, ensuring the blade withstands severe heat and stress without dropping segments.
Diameters range from 12" (300mm) up to 24" (600mm), with customizable segment heights of 10mm, 12mm, or 15mm depending on your project depth and longevity requirements.
