ATG LED Lighting S4-BO-S11G20-SBZ Square Straight Pole, 20" Length

ATG LED Lighting, S4-BO-S11G20-SBZ, 4" x 4" Steel Square Straight Pole, 20" Length, Bolt-On Moun, 11 Ga. Steel, Single/Parallel, Bronze

Features:

• Pole Shaft:
  • Straight poles are 4" square.
  • The Pole shaft is electro-welded ASTM-A500 Grade C steel tubing with a minimum yield strength of 50,000 psi.
  • On Tenon Mount steel poles, tenon is a high-strength pipe. The Tenon N is2-3/8" O.D. x 4-3/4" tall.
• Hand-Hole:
  • The standard hand-hole location is 12" above the pole base.
  • Have a 2" x 4" non-reinforced hand-hole.
• Base:
  • The Pole base is an ASTM-A36 hot-rolled steel plate with a minimum yield strength of 36,000 psi.
• Anchor Bolts:
  • Poles are furnished with anchor bolts featuring zinc-plated double nuts and washers.
  • Anchor bolts conform to ASTM F 1554-07a Grade 55 with a minimum yield strength of 55,000 psi.
• Ground Lug:
  • A ground lug is standard.
• Finishes:
  • Each shaft is purchased to a stricter straightness tolerance than specified on industry material standards. Shafts with dents, dings, roll marks, or patterns on the exterior surface are rejected. Shafts are stored indoors to prevent corrosion.
  • After connecting holes are cut and hand holes and baseplates welded to the shafts, each pole undergoes a thorough shot-peening process, resulting in a near-white surface. This procedure removes all dirt and scale and strengthens the surface of the steel by inducing a compressive
  • residual stress that helps prevent cracking and extend the life of the pole.
  • After shot peening, a neutral wash is applied, followed by a zirconium treatment that improves powder-coat adhesion and protects from corrosion.
  • Next, each pole is coated through electrostatic application of a polyester powder paint in standard bronze or the color approved by the customer. Paint thickness is measured in multiple locations along the pole to ensure specification adherence.
  • Finally, the pole is oven-baked to form a homogenous, non-porous surface and wrapped for shipment in a woven fabric sleeve to protect the finish during transit.
