How to select suitable electrical fitting accessories
To help procurement managers and project engineers identify the correct hardware configuration, Pubang provides straightforward technical coordination based on standard product specifications and material selections.
Define Application & Hardware Type
Identify the required product category (e.g., Pole Band, Cross Arm, Foundation Bolt, or Cable Bracket) based on the structural installation layout.
Specify Dimensions & Material Grade
Select from our standard dimensional range or request specific material grades (e.g., Q235B vs Q355B for steel profiles; Grade 4.6 vs 8.8 for anchor bolts; SS304 vs SS316 for corrosive zones).
Confirm Surface Finish & Anti-Corrosion Rating
Determine the appropriate protective coating according to environmental exposure (Hot-Dip Galvanizing compliant with ISO 1461 for outdoor utility lines, or Passivated Stainless Steel for chemical/coastal environments).
Review Project BOM & Receive Quotation
Submit your itemized product list (Bill of Materials) or technical requirements. Our sales team conducts a technical review and provides an itemized quotation within 12 hours.
