Unistrut P1100

Abhay Steels Manufactures and Distributes Unistrut P1100 Channel in India

Unistrut P1100 of the most robust and versatile profiles available for bolt-together framing is the Unistrut P1100. At Abhay Steels, we provide authentic P1100 channels that satisfy global requirements without sacrificing quality.

Unistrut P1100: What is it?

P1100 is a solid, 12-gauge (2.5 mm thick), 1-5/8 x 1-5/8 (41 x 41 mm) metal framing channel. P1100 is particularly robust for direct mounting and welding because it has a continuous solid profile without return lips, in contrast to the back-to-back P1000 series. You may achieve complete adjustability without drilling or welding on-site thanks to its continuous slot with inturned edges, which accepts conventional Unistrut spring nuts and fittings.

Consider it the heavy-lifting relative of the typical strut profiles. It is constructed from high-quality mild steel that complies with IS 5986 and ASTM A1011, and it is available in finishes appropriate for any setting.

We always have the P1100 in stock in a variety of finishes, so you never have to compromise on corrosion resistance:

Pre-Galvanized (PG) steel has an inexpensive, silvery finish and is suitable for indoor.
For outdoor and coastal work, hot-dip galvanized (HDG) offers better rust resistance.
Black or plain steel is suitable for painting or powder coating following manufacturing.

FAQ

What is a Unistrut P1100 channel's actual load capacity?

The type of loading, support conditions, and beam span all have a role. A one-meter-long, simply supported P1100 can support a load of roughly 200–250 kg, evenly distributed within its safe operating range. Refer to the official Unistrut load tables or contact our technical staff for project-specific figures.

Is it possible to utilize the P1100 back-to-back like the P1000?

Not at all. The P1100 is not intended to be welded back-to-back since it is a solid channel. The P1000 (12 gauge) or P2000 (14 gauge) profiles are ideal for back-to-back setups. When you need a single heavy-gauge component for embedment, clamping, or direct welding, use the P1100.

Is it possible to use regular Unistrut spring nuts and brackets with the P1100?

Indeed. Standard Unistrut M8, M10, and M12 channel nuts, spring nuts, and all corresponding brackets, clamps, and angle fittings are compatible with the slot dimensions (22.2 mm x 12.7 mm).

What lengths are available for P1100?

We have regular 3-meter (10-foot) lengths in stock, and for large orders, we will cut to precise millimeter lengths at no additional cost. Additionally, custom profile fabrication and hole-punching are offered.

Is it possible to obtain P1100 in stainless steel for a solar project along the coast?

Indeed. For corrosive environments, including offshore platforms, chemical facilities, and coastal solar farms, we frequently provide P1100 in SS304 and SS316. These are long-lasting without corrosion.
