We are looking for a metal fab shop to produce bicycle racks per the specifications below. The requirement is to produce 7,000 racks within a 5 month period this season. Hoping to place the business with a Mexican fab shop.
Shape: Circular Rack (diagram will be supplied upon request)
Rack Material: Hoop: 2” x 2” by 0.188” wall square tube
Reference: ASTM A500 Standard Specification for Welded and Seamless Carbon Steel Structural Tubing in Rounds and Shapes
Flanges: Two 5” x 6” (five inches by six inches) flanges, 3/8” thick plate; with three 9/16” mounting holes on each flange and one approximately 1” drainage hole aligned with the square tubing on each flange
Rack Coating: Zinc Coated (Hot-Dip Galvanized)
Reference: ASTM A-123 Standard Specifications for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products
Dimensions: Rack Width: 36” (to outside dimensions)
Distance Between Flanges (center to center): 18”
Alignment: Hoop shall be laterally aligned within a range of tolerance of 1” (e.g.: when hoop is laid flat, no part of the underside of the rack, excepting flanges, will rise higher than 1” off of flat surface).
Please see diagram with dimensions at end for additional information.
Mounting: Surface Mount
Fasteners: Fasteners not requested.
Welding: American Welding Society D1.1 Structural Welding Code Steel.
All welding shall be done by experienced and qualified welders in accordance with the standards and requirements of AWS D1.1 The Successful Contractor or manufacturer shall provide suitable means for clamping and holding members during the welding in order that warping or distortion of the structure shall be minimized. All welds shall have a 1/4-inch extra length at each end to allow for craters. Particular care shall be exercised to prevent undercutting or reducing the section of the material being welded. Grind exposed welds smooth.
Fabrication: Fabricate all steel for bicycle racks in accordance with the requirements of the Specifications. Identify all steel at the mill showing grade and yield points. Fabricate and assemble the steel segments in the shop to the greatest sizes possible without detriment to handling, transporting and erection in the field.
