Security Bars Drawing Approval: Review Before Production

Why Drawing Approval Matters

Security bars are made to measure, so every opening is different. A drawing turns your measurements and wishes into a plan that both you and the workshop can read in the same way. Reviewing it before production protects you from surprises such as bars that clash with a window handle, a gap that is too wide, or a fixing point that is not on solid wall.

Approval also records what was agreed. The drawing and written specification become the reference for manufacturing and installation, so there is no guesswork on either side.

What the Drawing Should Show

A clear drawing for security bars usually includes the following details:

• Overall width and height of each opening, with the measurement point marked
• Bar layout, spacing and direction (vertical, horizontal or decorative pattern)
• Fixing positions and the type of anchoring suited to your wall
• Material, profile size and surface finish
• Any opening sections, locks or quick-release parts

If something is missing from the drawing, ask before you approve it.

Checking the Measurements Before You Sign

Measurements are taken on site, and the drawing should match them exactly. Compare the drawing against the actual opening, including the frame, sill and any tiles or plaster that will change the final dimensions. Check that the measurement points are clearly marked so the installer knows where each dimension starts.

Pay attention to clearances around the window. Bars that sit too close can block opening or cleaning, while bars that are too far apart may not meet the safety expectations for a balcony or ground-floor window. Exact safety values are verified with the engineer, so raise any doubt during review.

Reviewing the Design and Appearance

Look at the drawing as you would look at the finished window. Consider how the bars line up with the frame, whether the pattern suits the building, and how the bars will look from the street. If you want a specific design, state it clearly in the written specification rather than relying on a general sketch.

Check the finish as well. Hot-dip galvanizing and powder coating each give a different look and level of protection, so confirm which one is included in your order before approval.

Approval, Production and Changes

Once you approve the drawing and specification in writing, production begins in the factory at 37 Rival Street, Tel Aviv. Changes after approval are possible but may require a revised drawing and can affect the schedule, so it is far easier to request corrections during the review stage.

Keep a copy of the approved drawing. It is the document your installer will follow on the day the bars are fitted.

Installation Check After Delivery

When the bars arrive, compare them with the approved drawing before installation begins. Confirm the dimensions, finish and number of pieces. The installer should then fix the bars according to the planned fixing points, check that they are level and secure, and confirm that the opening still works as expected.

• Compare delivered parts with the drawing
• Confirm fixing points match the wall type
• Test that opening sections and locks operate freely

Frequently asked questions

Do I have to approve the drawing before production starts?

Yes, approval is the step that confirms the design, dimensions and finish before any material is cut. This protects both you and the factory from misunderstandings.

Can I change the drawing after I approve it?

Changes are possible but may need a revised drawing and can affect the timeline. Requesting corrections during the review stage is the simplest route.

What if my measurements are slightly off?

Ask for the on-site measurement to be checked again before approval. Accurate measurements are the foundation of a good fit.

Who checks the safety requirements for the bars?

Safety requirements are checked with the engineer, and exact values are confirmed during the review. Raise any safety concern before you sign.

Common mistakes to avoid

Approving a drawing without checking the measurements against the real opening is the most common error. Skipping the finish and fixing details also leads to disappointment after installation.

Our recommendation

Read the drawing next to the written specification and walk through the opening in your head, checking every dimension, fixing point and finish before you sign.

Summary

Careful drawing approval confirms your measurements, layout, fixings and finish before production, so the security bars fit correctly the first time.
