Start with exposure, not appearance
Corrosion selection depends on the environment and contact materials. Simpson Strong-Tie identifies influences including salts, chemicals and dissimilar metals, and notes that even stainless steel can corrode. A shiny surface or the word “outdoor” is therefore not enough to determine suitability.
Technical reference: Simpson Strong-Tie: corrosion and anchor selection.
Ask which stainless steel is being offered
Stainless grades are not a single interchangeable category. Simpson Strong-Tie’s anchor guidance distinguishes 303/304, 316 and 410 for different material and product considerations. Its guidance is specific to its products and does not establish suitability for another supplier’s anchor. Request the exact grade and relevant product evidence for your enquiry.

Make the finish description measurable
For a galvanized option, ask the supplier to state the coating process and the specification against which the delivered product will be inspected. Keep different processes as separate options in the quotation. If the buyer has a coating requirement, attach it instead of relying on colour or a catalogue photograph.
Describe the body, expansion component, nut and washer individually where the specification requires it. A complete product record makes it easier to review a proposed change to one component without losing sight of the assembled anchor. Ask for the agreed records to accompany production, not only the initial sample.
Compare documented options
Use the same enquiry sheet for all suppliers. Leave the service-life decision with the project’s qualified reviewer and focus the purchasing comparison on what each supplier is actually offering.
- Intended environment and contact materials supplied by the buyer.
- Exact product reference and material details for the assembly.
- Coating process and acceptance requirements, if applicable.
- Product-specific installation and approval documents.
- Material or coating inspection records requested with the order.
- Sample identification, packaging and batch traceability.
Control wording in your own catalogue
Distributors should agree on product descriptions before placing a private-label order. Avoid changing “stainless steel” into a blanket “marine grade” or lifetime corrosion guarantee without applicable evidence. The wording on a box, website and quotation should describe the same supplied product.
A useful sample approval includes the material description, finish record and proposed label. If the supply option changes after approval, update those records together. This prevents the next batch from carrying an old claim that no longer matches the purchased item.
DURANCHOR lists stainless steel and hot-dip galvanized wedge anchor options. Send the exposure description and required specification when requesting a comparison, and ask which documents are available for each exact proposal.
Frequently asked questions
Does galvanized always mean hot-dip galvanized?
No. Require the supplier to identify the coating process explicitly rather than relying on the general word galvanized.
Is stainless steel corrosion-proof?
No. Assess the grade, product, exposure and contact materials against the relevant technical requirements.
