About this item

  • WELDABLE STEEL PLATES - These sturdy steel plates provide stable anchor to posts and structures on brick, concrete or cinder block surfaces. The metal plates are made of A36 steel, the same standard-grade alloy used in the construction of buildings.
  • HEAVY-DUTY - These flat metal plates have a wide range of general and industrial applications. They provide reliable support to structures subject to heavy vibration. A metal base plate may also be used as a mount for permanently installed equipment.
  • PAINT-READY - Each metal plate has a smooth, stained gray finish that provides an ideal base for painting. This allows for an even coat that prevents paint from peeling or chipping. A good top coat adds wear-resistant protection to the steel plate.
  • PLATE SPECS - Each A36 steel plate measures 4” X 4” and is 3/16” thick. Holes are pre-drilled on all 4 corners of the metal plate, each hole measuring 3/8” in diameter. Additional holes may be added to the plate using a heavy-duty, hard drill bit.
  • BOBCO METAL SOLUTIONS - We built our company from the ground up to become one of the oldest metal companies in Los Angeles, California. We are expert manufacturers, retailers and wholesalers of metals for all your industrial and construction needs.

The 4"x4" rolled steel plates are exactly as described. Clean, deburred, accurate per specifications. I will weld 2-1/4" steel tabs to these plates to fabricate chainplates to attach 1/4" SS twisted cable tensioners to cross brace 11' wooden deck posts on piers.

Looked at these and didn't look thick enough. Should have been 3/16 or .1875, actually came in at .145 to .147. Just be aware before you buy.
