When using 50 mm chipboard screws, it's essential to pre-drill holes to prevent splitting and to guide the screw for straight insertion. The pre-drilled hole should be slightly smaller than the screw's shank to allow for a tight fit The pre-drilled hole should be slightly smaller than the screw's shank to allow for a tight fit
In addition to their practicality, 38mm self-drilling screws are also known for their durability and strength
- The manufacturing process begins with the selection of high-quality raw materials, usually robust metals like steel or aluminum, ensuring durability and strength. These materials are then shaped and machined to exact specifications using state-of-the-art CNC (Computer Numerical Control) machines. Precision is paramount, as even the slightest deviation can impact the performance and safety of the tool.


button bits manufacturers. Atlas Copco button bits are designed to deliver exceptional performance and reliability in challenging drilling environments. The company's dedication to quality and customer satisfaction has earned it a solid reputation in the industry.
Available in both square and grid patterns, fiberglass grating is widely used due to its low maintenance cost combined with unmatched resilience. Unlike metal gratings, which in certain environments can require extended product life cycle; fiberglass grating is corrosion and rust free, making it more cost effective. Chemical attacks are also not an issue with fiberglass gratings, ensuring its durability. Ideal for the corrosive environment, FRP gives it the complete value for the money.
For this project, Jrain, with its good staff including sales, engineering, production, logistics and so on, did the engineering, fabrication, pre-assembly, packing and all necessary works from the beginingg to the end, and the finished launders got the appreciation from the end customer.

Fiberglass plates feature a non-conductive surface that makes them an economical and safe solution to walking surfaces. In caustic and/or acidic conditions, fiberglass plates provide a level of corrosion resistance that is unequaled and more cost effective than stainless steel. Fiberglass plate is available with a non-grit surface, or with a grit surface where anti-slip traction is needed. For more on fiberglass plates, click here.
