Procurement List: Categorized by Type
What does a door and window hardware procurement list include?
It is categorized by type: opening hardware (hinges/friction stays), locking hardware (lock bodies/handles), auxiliary accessories (seals/limiters), and project-specific requirements (quantities/specifications).
Industry experts note that the list should be evaluated by category—opening hardware (hinges/friction stays/transmission mechanisms), locking hardware (lock bodies/handles/locking points), auxiliary accessories (seals/limiters), and project-specific matching (quantities/specifications/profiles)—to ensure nothing is overlooked.
Categorized by Type
- Opening hardware: Hinges/friction stays (for opening)—list completely;
- Locking hardware: Lock bodies/handles (for locking)—list completely;
- Auxiliary accessories: Seals/limiters (accessories)—list completely;
- Project-specific matching: Quantities/specifications (matching)—verify;
- Categorized list: By category (checklist)—prevent omissions.
Evaluation Points
First, ensure opening hardware is fully listed.
List hinges/friction stays (opening) completely to avoid missing parts.
Second, ensure locking hardware is fully listed.
List lock bodies/handles (locking) completely to avoid missing components.
Third, ensure auxiliary accessories are fully listed.
List seals/limiters (accessories) completely to avoid incompleteness.
Fourth, verify project-specific matching.
Check quantities/specifications (matching) to avoid mismatches.
Tips to Avoid Pitfalls
First, avoid “missing hardware items.”
Missing hinges causes work delays; ensure the opening hardware list is complete.
The second issue is “incomplete locking.”
This involves missing lock bodies (or inconsistencies) and incomplete locking component sets.
The third issue is “quantity errors,” involving discrepancies (requiring rework) and the need to verify matching components.
Trends and Recommendations
Procurement lists for door and window hardware are moving toward digitalization, characterized by the use of standardized templates and data-driven integration with BIM.
For purchasers, the recommendation is to “list items by category, include all accessories, and verify matching components.”
A comprehensive list ensures the procurement process is completed efficiently in a single step.
