Safer Walking Surface for Trench Covers and Fiberglass Walkways
A coarse, gritted epoxy coating enhances traction.- Another advantage of top hammer drilling with top hammer bits is the ability to drill holes at a faster rate compared to other drilling methods. The high impact force of the hammer, combined with the durable and wear-resistant properties of the top hammer bit, allows for efficient drilling in various rock conditions
top hammer bit. This results in reduced drilling time and increased productivity on-site.





At the begining of 2023, our company completed one FRP DN6m thickener tank, as a part of Thickener System, for our USA customer.
molded frp gratings are manufactured in a one piece construction which results in a bi-directionally strong product. This allows openings for piping or cables in the grating of up to 10” without any additional support required (may vary depending on grating depth and location of opening). During the molded manufacturing process, the continuous fiberglass rovings are completely covered in a high percentage of resin, 65% by volume. With this high resin content, molded gratings are the most chemically resistant gratings offered and are often used in caustic chemical environments without hesitation.
