Product Description

Service Process for High-Strength Stainless Steel Expansion Anchors for Construction

1. Pre-Production Collaboration

(1) Requirement Confirmation
Confirm anchor type, nominal diameter, length, expansion mechanism, load requirements, installation conditions, application environment, order quantity, and delivery schedule.

(2) Drawing & Specification Review
Review technical drawings or specification sheets covering anchor structure, thread standards, expansion sleeve design, and tolerance requirements.

(3) Application & Feasibility Analysis
Evaluate suitability for concrete or masonry substrates, installation depth, and mechanical expansion performance.

2. Manufacturing Process Planning

(1) Material Selection
Select appropriate stainless steel grades such as A2 (304) or A4 (316) based on strength, corrosion resistance, and application environment.

(2) Process Planning
Plan CNC turning, cold forming, threading, and assembly processes for bolts, expansion sleeves, cones, and washers.

(3) Process Optimization
Optimize forming and machining parameters to ensure consistent expansion performance and dimensional accuracy.

3. Production & Quality Control

(1) Manufacturing & Assembly
Produce stainless steel expansion anchors through precision machining, forming, and controlled assembly of all components.

(2) Surface Condition & Cleaning
Ensure clean surfaces free from burrs and sharp edges to support safe installation and reliable expansion.

(3) Inspection & Verification
Inspect critical dimensions, thread accuracy, material integrity, and assembly consistency using calibrated measuring tools.

4. Packaging & Delivery

(1) Optional Surface Treatment
Passivation or polishing can be provided to enhance corrosion resistance and surface quality.

(2) Packaging
Package anchors in bulk cartons or customized packaging to protect threads and expansion sleeves during transport.

(3) Delivery
Deliver finished stainless steel expansion anchors according to agreed logistics terms, suitable for construction site use.
