Material selection for integral drill rods is crucial to their performance and longevity. Typically made from high-speed steel (HSS) or carbide, these rods are heat-treated to withstand the stresses of high-speed drilling and the friction generated during thread formation. HSS offers a good balance of toughness and hardness, while carbide provides superior durability and cutting efficiency, making it ideal for drilling through harder materials.

It was not until the development of the hydraulic drifter in the 1950s that rock drilling truly entered the modern eradrifter for rock drill. This innovative tool used high-pressure hydraulic fluid to power a piston that rotated the drill bit, allowing for much greater penetration rates and precision. The hydraulic drifter quickly became the go-to tool for drilling holes in hard rock, paving the way for many of the major engineering projects of the time.

FRP Gratingwhether formed through molding or pultrusion processes, offers significant benefits in various industrial and commercial applications. The high strength of fiberglass and its corrosion resistance make it ideal for harsh environments such as power plants, mining areas, and oil refineries. Additionally, its lightweight nature facilitates easy mobilization, installation, and maintenance, while the anti-slip surface ensures user safety. Another advantage is its ability to be produced in various sizes and designs according to needs, enhancing its usage flexibility. With a combination of strength, durability, and flexibility, FRP grating becomes a reliable and efficient choice for various structural needs in industrial and commercial sectors
