Shalan Steel, located in Kuala Lumpur, Malaysia, has built a solid reputation as a reliable manufacturer and supplier of high-quality steel products that adhere to both local and international standards. The company is dedicated to providing dependable steel solutions for clients in the construction, infrastructure, and industrial sectors. One of their most popular products is the Carbon Steel BS1387 Pipe, which is a go-to choice for a variety of general-purpose applications. Renowned for its durability, ease of installation, and compliance with British Standards, this pipe is a vital option for plumbing, water conveyance, and light structural projects throughout Malaysia and Southeast Asia.
The Carbon Steel BS1387 Pipe is crafted in line with British Standard BS1387, which outlines the requirements for screwed and socketed or plain-end steel tubes. These pipes come in three classes: Light (L), Medium (M), and Heavy (H), each featuring different wall thicknesses. Typically made from mild steel with a carbon content of up to 0.20%, they boast good tensile strength (usually around 320–460 MPa) and impressive ductility. The material is suitable for threading and galvanizing, which enhances corrosion resistance when necessary. BS1387 pipes are often supplied either in their natural black (uncoated) state or hot-dip galvanized for extra protection.
