UPN Channels (U Sections)
Masteel are suppliers of UPN Channels (commonly known as ‘U Sections’) which are used throughout the construction industry. These sections are to the continental specification and therefore, unlike UK sections, are truly metric.
Our UPN Channels are high yield making them ideal for use in cold working conditions. Low temperature testing is available and the customer can have their steel tested to their designated temperature, e.g. -20°C, -30°C or -50°C.
