Read MoreWhen it comes to scaffolding systems, BS1139 scaffolding tubes and couplers are among the most trusted standards globally, ensuring structural integrity and worker safety in construction projects. These components form the framework for temporary structures used in building, maintenance, and industrial applications. Why BS1139 Scaffolding Tubes & Couplers? The BS1139 standard specifies the requirements for steel tubes and couplers…
Read MoreASTM A276 is a standard specification that sets the requirements for stainless steel bars and shapes, including the popular Type 316 grade. While this standard directly covers solid forms like rounds and squares, the high-quality ASTM A276 316 stainless steel material is also precisely manufactured into high-performance tubes and pipes for specialized applications. This grade is an austenitic stainless…
Read MoreNavigating the world of European steel standards can be complex. For professionals sourcing structural components, understanding the distinction between EN 10219 and EN 10025 is crucial for project success. While both are fundamental in the European market, they govern completely different aspects of steel products. In short, EN 10025 defines what the steel is, while EN 10219 defines what…
