Our Profile Cutting Tolerances

Materials we cut

As we have 4 different flatbed cutting methods together under one roof, we have the ability to profile an exhaustive range of metal and non-metallic materials. Our combined processes mean we can cut material from 0.1mm thin to 270mm thick. We keep a large material range in stock and anything we don’t, we can usually source within 24 – 48 hours. Equally, we’re happy to profile cut your free issue material if preferable. Even if it doesn’t appear on the list below, typically, if we can source it, we can cut it. 

Profile Cutting Tolerances

At Charles Day Steels, we understand that precision is paramount when it comes to metal cutting. Whether you require laser cutting, waterjet cutting, flame cutting, or plasma cutting services, you can trust us to deliver exceptional results. We adhere to stringent tolerances in accordance with BS EN 10051:2010 for thicknesses, and BS EN 10029:1991 for flatness to ensure your parts meet the highest standards of accuracy and quality.

Laser Cutting

Laser cutting has the ability to effortlessly cut through a range of materials with a precision that is lacking in more traditional areas of profiling technology. Due to it’s fast, effective cutting, incredible accuracy and repeatability, Laser profiling is quickly becoming one of our more popular cutting services.

Laser Profile Cutting Tolerances

With unrivaled capacity and profiling facilities, our laser cutting machines are capable of handling sheet sizes of up to 6 metres x 2.5 metres, and profile cutting tolerances of +/- 0.12mm. Our laser cutting tolerances are in strict accordance with relevant guidelines to guarantee accurate and consistent cuts across a range of materials.. For further guidance and information, please see our dedicated Laser Profile Cutting Tolerances page.
