The Unistrut P1000 channel is a solid steel framing member used across construction and industrial projects for support work of every kind. Facility managers, contractors, and engineers choose this size when a project calls for a strut that stays strong, dependable, lightweight, and affordable. This guide covers the channel’s full specifications, dimensions, load ratings, and finish options. It also walks through the steps for ordering the product from Steinco Industrial Solutions.

P1000 belongs to a family of channel sizes, each suited to different loads and budgets. This piece breaks down the exact measurements, weight, and strength ratings needed for accurate specification. It also covers available finish options for indoor, outdoor, and specialized environments. Ordering steps close out the piece so a project moves from planning to purchase in a few simple steps.

What Is Unistrut P1000 Channel

Unistrut P1000 channel forms the base member of the 1 and 5/8 inch metal framing platform. Crews use spring nuts and bolts to build support structures with this system, avoiding the need for on-site welding equipment. The design offers a strong and easy-to-handle option for many commercial and industrial projects. Many project specifications name this size as the default strut option when a project leaves the size choice open.

This channel supports conduit runs, cable trays, pipe hangers, HVAC racks, signage posts, and shelving frames across a wide range of facilities. Steinco stocks solid, slotted, double-slotted, and round-hole versions for quick shipping. Teams working under federal contracts can also source this channel through our GSA Schedule. The steady demand for this size comes from its balance of price, strength, and availability.

Unistrut P1000 Dimensions and Specifications

Unistrut P1000 channel measures 1 5/8 inches by 1 5/8 inches and uses 12-gauge steel. The cross-sectional area is 0.555 square inches, giving the channel steady strength for its size. Standard stock lengths are 10 and 20 feet, with custom-cut lengths available to order. Slotted versions feature 9/16-inch by 1 1/8-inch slots set on 2-inch centers.

The 12-gauge wall sets this channel apart from lighter options such as the P1100, built from 14-gauge steel, and the P2000, built from 16-gauge steel. All three share the same outer profile, so the gauge marking on a spec sheet matters. Ordering the wrong gauge changes the load rating, even when the outer size looks the same. Reading the full part number on a drawing keeps a project on the correct spec.

Load Capacity and Weight Per Foot

Unistrut P1000 channel weighs about 1.90 pounds per foot, or 190 pounds per 100 feet, in its solid form. Slotted versions weigh slightly less because the slots remove material. On a 10-foot simple span, the beam load rating approaches 340 pounds before deflection limits take over. Shorter spans raise that number, and longer spans lower it, so span length always affects the final rating.

Column load capacity depends heavily on the unbraced height of the run. A 24-inch unbraced column carries several thousand pounds, while a 10-foot unbraced column carries much less. These figures come from engineering data built on cold-formed steel design standards from the American Iron and Steel Institute. Checking the load tables against the exact span and bracing plan for a project gives the clearest answer for any load-bearing use.

Seismic bracing, elevated platforms, and overhead pipe racks all call for accurate load planning before installation. Our engineering team runs these calculations against the exact span and bracing setup for each order. This step protects the project from guesswork and keeps every support sized correctly. Reaching out early in the design phase saves time once material orders go out.

Material and Finish Options

Unistrut P1000 channel ships in several finishes to match a range of settings. The standard zinc-coated finish suits general indoor use and regular outdoor exposure. A heavier zinc coating suits outdoor, damp, or corrosive settings that require stronger protection. A painted option gives indoor projects a clean, uniform look when appearance matters as much as strength.

Stainless steel P1000 channel fits food processing plants, pharmaceutical facilities, wastewater sites, and marine settings where standard coatings fall short. A special-order PVC-coated version handles chemical exposure and electrical isolation needs. Plain uncoated channel works well for projects planning a paint job after fabrication. Choosing the right finish up front, whether the channel sits indoors or faces outdoor weather, keeps maintenance costs low over the structure’s life.

Hole pattern choice shapes how a crew connects fittings on site. Solid channel keeps a clean, hole-free surface for custom drilling. Slotted channel offers continuous slots for field-adjustable connections, while round-hole and double-slot versions suit specific fitting and hanger types. Choosing the right pattern before an order goes out saves drilling time once the material reaches the job site.

How To Order Unistrut P1000 From Steinco

Ordering Unistrut P1000 channel from Steinco starts with confirming the finish, length, and hole pattern called out in a project spec. Our team pulls the correct match from a drawing when a customer sends one over. Standard lengths ship within days from our Ashland, Ohio location. We also offer pierced or double-slot versions and full combination members.

Federal buyers can source this channel and the full Unistrut line through our GSA Multiple Award Schedule contract. Large or engineered orders, such as seismic bracing packages, kitted assemblies, and custom cut lengths, move through our design, procurement, and installation service as one project. This turnkey path keeps a single point of contact in place from the first drawing to the final installed support. Reaching our team early in the planning stage keeps timelines on track and pricing clear from the start.

Frequently Asked Questions

What are the dimensions of Unistrut P1000 channel?

This channel measures 1 5/8 inches by 1 5/8 inches and uses 12-gauge steel. The cross-sectional area sits at 0.555 square inches. Standard stock comes in 10-foot and 20-foot lengths, with custom-cut lengths available.

How much weight can this channel hold?

On a 10-foot simple span, the beam load rating for this channel reaches close to 340 pounds before deflection limits take over. Column load capacity changes with the unbraced height of the run, so shorter runs carry much more. Checking the manufacturer load tables against the exact project setup gives the clearest number for any job.

How much does this channel weigh per foot?

Solid Unistrut P1000 channel weighs about 1.90 pounds per foot, or 190 pounds per 100 feet. Slotted versions weigh slightly less because the slots remove material. This steady, predictable weight makes shipping and handling calculations simple for any crew.

What sets P1000 channel apart from P1100 channel?

P1000 channel uses 12-gauge steel, giving it a higher load rating for its size. P1100 channel uses a lighter 14-gauge steel, a good fit for lighter-duty runs. Both channels share the same 1 and 5/8 inch by 1 and 5/8 inch outer profile, so checking the gauge marking on a spec sheet stays important.

Is this channel available in stainless steel?

Stainless steel P1000 channel is open for order and fits settings where standard coatings fall short. Food processing plants, pharmaceutical facilities, wastewater sites, and marine settings often call for this option. Our team can confirm lead times and pricing for stainless orders on request.

What finish options come with this channel besides galvanized?

Along with the standard zinc-coated and heavier zinc-coated finishes, this channel comes in a painted option for a clean indoor look. Plain uncoated steel suits projects planning their own paint job after fabrication. A special order PVC-coated version handles chemical exposure and electrical isolation needs.

Can this channel be ordered in custom lengths?

Custom cut lengths and kitted assemblies are available alongside the standard 10-foot and 20-foot stock. This option lets field crews spend more time installing and less time measuring and cutting on site. Sending exact project measurements helps our team prepare the right cut list before shipping.

Does Steinco carry fittings and hardware for this channel?

Steinco carries the full range of channel nuts, brackets, and fittings built for the 1 and 5/8 inch Unistrut system. This selection lets a customer source the complete assembly, channel, nuts, and connectors from one supplier.
