The Function of Hidden Screws in GRC Interlock and GRC T Line

The hidden screw system is an installation technique that provides a neat and seamless finish. One building material that utilizes this technique is GRC board (cement board). By using this method, the need for compound or putty to cover screw heads is significantly minimized.

Certain GRC board products, specifically GRC Interlock and GRC T-Line, are designed to take full advantage of this hidden screw system. Both feature a specialized tongue and groove profile (lower tongue) for a precise interlocking connection. Unlike standard flat edged boards, the unique side profiles of GRC Interlock and GRC T-Line allow boards to lock together seamlessly, creating a distinctive "waterline" aesthetic at the joints.

Advantages of GRC Interlock & GRC T-Line

Our building materials simplify the installation process while providing a much neater and sturdier result compared to conventional boards. Additionally, these products minimize material movement, which helps prevent cracks. They also accelerate the workflow since there is no need to fill every screw hole individually.

Applications in Building Projects

Our products are highly versatile and flexible, making GRC Interlock and GRC T-Line suitable for both interior and exterior applications. GRC boards are termite-resistant, mold-resistant, moisture-resistant, and durable enough to withstand extreme weather conditions.
