# Pipes and Tubes

OD 15.88 - 60.3 mm WT 1.24 - 6 mm ASTM A213 / ASTM A789 / EN 10216-5

## Product Description

Our integrated manufacturing edge gives us the ability to produce steel in a variety of finishes, surface options and profiles

Composition limits for the grades in the tube and pipe programme are in the [grade reference](https://www.laxconsteels.com/grades/). Weight per metre from outside diameter and wall thickness is in the [pipe and tube weight chart](https://www.laxconsteels.com/weight-charts/#seamless-pipe-and-tube-weight), and the [weight calculator](https://www.laxconsteels.com/weight-calculator/) takes the same two numbers.
