From the heart of Hamilton, Latham Steel has built a reputation for reliability, supplying high-quality steel products across New Zealand. We are particularly proud of our Carbon Steel BS1387 Pipe, a standard that has stood the test of time. Known for its exceptional durability and cost-effectiveness, this pipe is a cornerstone in numerous industrial and construction applications. Our team ensures every length we supply meets the rigorous standards our customers depend on, providing a dependable solution for projects both large and small, right from our local base.
The composition of BS1387 pipe is straightforward yet robust, primarily consisting of carbon steel which gives it tremendous strength. This standard carefully defines its mechanical properties to ensure consistency, including a specified minimum yield strength that guarantees it can handle significant pressure and stress. The pipes are tested for their ability to be bent and flattened without failing, confirming their toughness. These controlled characteristics make it a predictable and reliable choice for engineers who need a material they can count on for demanding environments.
