P1000 channel, a 1 5/8″ square structural channel, is a versatile component in various construction and industrial applications. This article provides a comprehensive overview of P1000 channel fittings, including material specifications, available finishes, application examples, and important design considerations such as bolt torque and load capacity. Understanding these aspects is crucial for ensuring safe and effective utilization of P1000 channel systems.
P1000 Fitting Materials and Finishes
Fittings for P1000 channel are typically constructed from hot-rolled steel that undergoes pickling and oiling for a smooth, scale-free surface. These steel components adhere to industry standards like ASTM A575, A576, A635, A1011 SS GR 33, A1011 HSLAS GR 45, or A36, guaranteeing consistent quality and performance. All fittings meet or exceed the physical properties of ASTM A1011 GR 33. Alternatives to steel, such as stainless steel, aluminum, and fiberglass, may also be available.
Several finishes are offered to enhance durability and corrosion resistance:
- Green Powder Coat (GR): A commercially standard powder coating providing a protective layer.
- Electro-galvanized (EG): Conforms to ASTM B633 Type III SC1 for enhanced corrosion protection.
- Hot-dipped galvanized (HG): Meets ASTM A123 or A153, offering superior corrosion resistance in harsh environments.
- Plain (PL): Unfinished steel, suitable for applications where corrosion resistance is not a primary concern.
- Unistrut Defender (DF): Complies with ASTM A1059 or A1046, offering premium corrosion protection.
It’s important to note that the Perma Green finish is a commercial grade and minor imperfections like scuffs or scratches may be present. Touch-up paint can be used to address aesthetic concerns.
P1000 Channel Applications and Design Considerations
P1000 channel fittings are designed for diverse applications, often illustrated with the P1000 channel itself. These fittings enable the construction of robust support systems, framing, and other structures. A common connection method involves 9/16″ diameter holes using 1/2″ x 15/16″ hex head cap screws and corresponding nuts (P1010, P3010, P4010, or P5510), which are ordered separately.
Proper bolt torque is crucial for structural integrity. The recommended and maximum torque values for various bolt sizes are provided in the following tables:
| Bolt Size | 1/4″-20 | 5/16″-18 | 3/8″-16 | 1/2″-13 | 5/8″-11 | 3/4″-10 |
|---|---|---|---|---|---|---|
| Rec. Torque Ft/Lbs | 6 | 11 | 19 | 50 | 100 | 125 |
| (N•m) | (8) | (15) | (26) | (68) | (136) | (170) |
| Max Torque Ft/Lbs | 7 | 15 | 25 | 70 | 125 | 135 |
| (N•m) | (9) | (20) | (34) | (95) | (170) | (183) |
| Bolt Size | 1/4″-20 | 5/16″-18 | 3/8″-16 | 1/2″-13 | 5/8″-11 | 3/4″-10 |
|---|---|---|---|---|---|---|
| Set Screw Torque In/Lbs (N•m) | 6 (8) | 11 (15) | 19 (26) | 50 (68) | 100 (136) | 125 (170) |
Furthermore, dimensions are provided in both imperial (inches) and metric (millimeters) units for accurate fabrication and installation. Design load data, incorporating a safety factor of 2.5, assists engineers in determining the appropriate application for each fitting.
Beam Clamp Considerations for P1000
Beam clamps designed for use with W, M, S, and HP shape beams, as well as standard C and MC channels, angles, and structural tees, often complement P1000 channel systems. These clamps are typically used in pairs, mounted in opposing directions for secure attachment. Note that beam clamps with a hot-dipped galvanized (HG) finish usually come with electro-galvanized (EG) hardware. Stainless steel hardware options may be available upon request.
Conclusion
Understanding the specifications and applications of P1000 channel and its associated fittings is essential for successful project implementation. By considering material selection, finishes, torque specifications, and load capacities, engineers and contractors can ensure the structural integrity and longevity of their designs. Remember to consult manufacturer documentation for comprehensive details and specific application guidelines.
