Light Pole with Bracket Arms - Multi-Fixture Mounting Options

Product details description

　　Light pole with bracket arms systems provide comprehensive outdoor lighting solutions for parking lots, roadways, parks, and commercial facilities, offering adjustable fixture mounting capabilities while maintaining structural integrity and aesthetic consistency across large-scale installations. These poles conform to ASTM A595 specifications for cold-formed welded and seamless carbon steel structural tubing, manufactured from steel grades including ASTM A572 Grade 50 with minimum yield strength of 50,000 PSI and ASTM A500 Grade C with minimum yield strength of 54,000 PSI. Pole dimensions utilize tapered octagonal or round configurations with base diameters ranging from 4.5 inches to 12 inches, wall thickness options from 11 gauge to 7 gauge, and overall heights from 20 feet to 50 feet accommodating various lighting requirements. Hot-dip galvanization follows ASTM A123 standards with zinc coating weights of 3.9 oz/sq ft minimum, providing corrosion protection service life exceeding 25 years in outdoor environments. Bracket arm configurations include single-arm designs supporting one fixture, double-arm configurations for opposite fixture mounting, and trident designs accommodating three fixtures with 120-degree spacing for 360-degree illumination coverage. Arm projections extend from 3 feet to 8 feet from pole centerlines, allowing precise fixture placement while maintaining proper illumination spacing and reducing dark zones.

　　Advanced light pole systems incorporate enhanced structural and electrical features including base plates conforming to ASTM A36 specifications with minimum thickness of 3/4 inch, anchor bolts utilizing ASTM A307 threaded rods with 24-inch minimum embedment depths, and internal wiring raceways preventing cable exposure and reducing maintenance requirements. The bracket arm design utilizes ASTM A500 structural tubing with moment connections ensuring load transfer without deflection under wind loads exceeding 150 mph when designed per AASHTO LRFD Bridge Design Specifications. Fixture mounting hardware includes stainless steel bolts meeting ASTM A193 specifications, adjustable slip-fitters allowing fixture positioning adjustments, and vibration dampening systems preventing premature lamp failure due to wind-induced oscillations. Wind load calculations follow ASCE 7-16 requirements for various exposure categories, with importance factors considering critical infrastructure applications, and safety factors of 1.67 for structural components per AASHTO specifications. Installation procedures require proper foundation design utilizing reinforced concrete footings, precise pole alignment using surveying equipment, and professional wiring techniques meeting NEC Article 600 requirements for outdoor lighting circuits. Quality assurance includes dimensional verification per ASTM specifications, galvanization testing per ASTM A123, and structural testing using calibrated load cells for wind load capacity verification.
