Product overview
C-Channels (Cold-Formed): overview and uses
A C-channel is a light steel section roll-formed from flat strip into a "C" shape with a uniform wall thickness and sharp bends, supplied plain or with small inward lips. It is lighter than a hot-rolled UPN channel and is the usual choice for purlins, girts and light framing.
Cold-formed C-channels are made by bending steel strip at room temperature, so the wall thickness is the same all round and the corners are tight. This gives a high stiffness for the weight, which is why C sections are used for roof purlins, wall girts, mezzanine joists and light frames.
They are different from hot-rolled channels. A UPN channel has tapered inner flanges and rounded roots, and a PFC has thick parallel flanges; both are heavier sections for structural members. OGB supplies cold-formed C-channels in black steel or pre-galvanized Z275 steel, cut and punched to your schedule.
Characteristics
Why C-Channels works in the UAE

Questions
C-Channels (Cold-Formed): common questions
What is the difference between a C-channel, a UPN and a PFC?
A C-channel is cold-formed from thin strip with a uniform wall and sharp corners. A UPN is hot-rolled with tapered inner flanges, and a PFC is hot-rolled with parallel flanges. UPN and PFC are heavier structural members; C-channels are used for purlins, girts and light framing.
Should I choose a lipped or a plain C section?
Lips stiffen the flanges, so lipped C sections carry more load as purlins and girts for the same thickness. Plain C sections are used for trims, frames and fabrication where lips are not needed.
Pre-galvanized or hot-dip galvanized?
Pre-galvanized Z275 strip is economical and suits most roof and wall framing. Hot-dip galvanizing after fabrication gives a thicker coating, including on cut edges and holes, for harsh coastal or industrial sites.
