Pressure Vessel Plate or Boiler Plate?

At Brown McFarlane we make a distinction between boiler plates and pressure vessel plates. Some other steel plate companies class everything as pressure vessel plate: there is no right and wrong about this.

The most important thing to know as a potential customer of Brown McFarlane is that we stock, process, and distribute all of the popular grades of Boiler and Pressure Vessel specifications like ASTM A516, ASME SA516, EN 10028-3, and BS 1501. You may call the steel whatever you want and leave us to worry about matching our stocks to your requirements.

About our Pressure Vessel Steel Plate

Our plates are sourced from the highest quality steel manufacturers in the world and, like all our suppliers, these manufacturers have been vetted and assessed by our procurement team.

As well as being available from stock all steel plate can be cut to size and shape according to your fabrication and design requirements and all work is governed by our independently accredited and regularly audited quality systems to ISO 9001.

Brown McFarlane’s extensive supply partnerships with many of Europe’s leading steel plate manufacturers offer the opportunity for us to supply non-stock items or non-standard sizes directly from the steel mill to our customers. Using this form of supply it is often possible to deliver much faster than “standard” mill lead times.

All of our plates and plate products can be delivered to customers anywhere in the world using the services of our own in-house logistics staff.
