Dacromet Steel Structure Bolts

Dacromet steel structure bolts are high-performance fasteners used in outdoor steel structures, bridges, towers, and photovoltaic power plants, where high corrosion resistance is required. While retaining the high preload and anti-slip properties of traditional steel structure bolts, these bolts utilize a Dacromet coating to address issues such as hydrogen embrittlement, unstable torque coefficient, and rough appearance inherent in traditional hot-dip galvanized steel structure bolts. In cross-sea bridges, coastal power plants, chemical plant steel structures, and wind turbine towers in high-altitude and cold regions, Dacromet steel structure bolts resist chloride ion corrosion, freeze-thaw cycles, and industrial atmospheric erosion. Notably, the torsion-shear type Dacromet steel structure bolts, when combined with the Dacromet coating, exhibit stable fracture torque at the sputter head, and the coating does not peel off, making construction quality easier to ensure.

Product Feature

Precise Torque Control: Uniform coating thickness ensures a stable torque coefficient during installation, making it easier for construction personnel to control the preload.

Excellent Anti-Slip Performance: The coating provides a strong connection when used with sandblasted steel plate friction surfaces, preventing slippage.

No change to thread size: The coating is very thin, allowing for direct use with ordinary nuts; unlike hot-dip galvanizing, a larger clearance nut is not required.

Beautiful appearance: The uniform and delicate silver-gray matte surface offers a more premium look than the rough zinc layer of hot-dip galvanizing, making it suitable for exposed steel structures.

Strong weather resistance: It will not powder or crack under extreme cold, high temperatures, or strong ultraviolet radiation, making it suitable for various harsh climates.
