Procurement Due Diligence
Frequently Asked Questions (FAQ)
Clear, technical answers to critical engineering, manufacturing, and international shipping questions commonly asked by procurement managers and logistics consultants.
Q1
What steel grades and safety standards does HEDA use for structural columns?
We primarily use cold-rolled Q235B and high-yield Q355B structural steel from top Chinese mills. Uprights and box beams are engineered to conform with EN 15512, SEMA, and RMI standards. Every production heat number is accompanied by original steel mill test certificates verifying tensile and yield limits.
Q2
What data is needed for HEDA to create a free warehouse CAD layout?
To generate an optimized CAD design, please share your architectural floor plan (DWG or PDF) noting internal column spans, effective clear ceiling heights, pallet dimensions (W x D x H, including overhang), maximum gross pallet weight, and the turning radius and mast reach of your forklift fleet.
Q3
How does HEDA protect steel racking from rust in humid or coastal areas?
Every component undergoes an automated multi-stage immersion treatment including degreasing, pickling, rinsing, and phosphating. This forms an anti-corrosion barrier prior to thermosetting epoxy-polyester powder coating. For cold storage and outdoor applications, hot-dip galvanizing is also available.
Q4
What is your typical production lead time and loading capacity per 40HQ container?
Standard warehouse systems require 15 to 25 production days depending on total project tonnage. A standard 40HQ container typically accommodates 22 to 25 metric tons of racking, depending on port weight limits and component nesting profiles.
Q5
Do you provide installation drawings, hardware, and field guidance?
Yes. Every export order includes numbered 3D structural schematics, bolt torque specifications, frame assembly guides, and anchor point details. For large-scale projects, on-site HEDA engineering supervisors can be dispatched to oversee local contractor installation teams.
Q6
Can HEDA manufacture OEM customized hole pitches and custom colors?
Yes. We offer fully customized OEM/ODM fabrication, including 50mm, 75mm, and 76.2mm (3-inch) column punching pitches, teardrop profiles, custom footplate stamping, and RAL-specified electrostatic powder coatings to align with corporate warehouse branding.
