Confirm Stainless Steel Specifications and Start Fabrication

t474-44

To confirm stainless steel specifications, lock in the grade, finish, exact dimensions, fixing method and installation details on a written, signed drawing. Once that specification is approved, the factory can cut, weld, finish and schedule production without rework.

Why a Locked Specification Comes First

Stainless steel work is made to measure, so every decision made before production affects cost, timing and fit. A specification that changes after cutting starts usually means scrapped material or a delayed delivery. For project managers, the goal is a single approved document that everyone on site and in the workshop works from.

Before sending the order, confirm that the drawing reflects the final design, not an earlier revision. Check that the architect, contractor and client have seen the same version.

Key Items to Confirm

Review each item below and record it in writing:

Stainless steel grade and the environment it will face (indoor, coastal, humid or polluted air)
Surface finish, such as brushed, polished or satin
Exact dimensions, including tolerances and reference points
Fixing method: anchors, base plates, embedded sleeves or welded connections
Glass, infill or mesh types if the work includes them
Handrail or guard heights and spacing, checked against the applicable standard with the engineer

Measurement and Drawing Review

On-site measurement should be done or verified after the substrate is finished, because plastering, tiling and floor levels can change the final dimensions. Record measurements on the drawing with the date and the person who took them.

Our team prepares a drawing and written specification based on that survey. Read both carefully. Pay attention to notes on welds, edges, visible joints and any areas where the stainless steel meets other materials, since these details are often the source of later disagreements.

Written Approval and Sign-Off

Once the drawing and specification are final, ask the client, and the architect or engineer where relevant, to approve them in writing. An email reply or a signed copy is enough, as long as it clearly references the drawing revision.

Keep the approved revision number on the order. If any later change is requested, issue a new revision and confirm it the same way. This protects the schedule and makes it clear who approved what.

Production Steps After Approval

After approval, the work moves into the factory. Stainless steel is cut, formed and welded to the drawing, then ground and finished to the agreed surface. Welds are dressed so they blend with the material where the finish is visible.

Project managers should ask for an estimated production window once approval is received, and note any dates that depend on other trades, such as glass delivery or site readiness.

Installation Coordination

Installation works best when the site is ready. Confirm that openings, floors and anchor points are complete, and that access for lifting and fixing is clear. Stainless steel should be protected from cement, plaster and other contaminants during construction, as these can stain the surface.

Frequently asked questions

Which stainless steel grade should I specify?

The right grade depends on the environment, especially exposure to salt air or humidity. Discuss the location with our team so the grade is matched to the conditions and the approved drawing states it clearly.

Can dimensions change after production starts?

Changes after cutting or welding are costly and can delay delivery. Confirm measurements and the drawing revision before production begins, and treat any later change as a new revision.

Do I need an engineer to approve the specification?

For railings, guards and structural elements, it is wise to have the engineer or architect review the drawing. Exact technical values should be checked with the engineer rather than assumed.

How do I protect stainless steel during construction?

Keep finished pieces covered and away from cement, plaster and dust. Remove protective film only when the site work is complete and the surface is clean.

Common mistakes to avoid

Starting production from an unapproved or outdated drawing is the most common and expensive error. Also avoid measuring before finishes are complete, since small changes in the substrate can throw off the fit.

Our recommendation

Send one approved drawing with a revision number and a signed confirmation before production starts. Ask the factory to confirm the grade, finish and fixing method in writing, so nothing depends on memory.

Summary

Confirm grade, finish, dimensions and fixings on a signed drawing before fabrication starts, and keep the revision number on every later change.
