Security Bar Supplier Questions to Ask Before You Sign

t259-3

Before signing with a security bar supplier, ask how they measure, what materials and finishes they use, how the bars are fixed to your wall or frame, and who handles drawings and installation. A good supplier answers these clearly in writing, so you know exactly what you are approving.

Ask how they measure and confirm the design

Ask whether the supplier measures on site or only works from your photos. Photos alone rarely show the exact opening, uneven walls, or the position of shutters and handles. A reliable supplier visits, measures, and then sends a drawing and written specification for you to approve before production starts.

Is the on-site measurement included?
Will I receive a drawing before production?
Who checks the final dimensions?

Ask about materials and their suitability

Security bars are commonly made from iron or aluminum, and each suits different conditions. Ask which material they recommend for your exposure, whether the profiles are solid or hollow, and what the bar spacing will be. Ask them to explain why the material fits your building rather than only quoting the cheapest option.

Ask about finishing and corrosion protection

Metal bars need protection, especially near the coast or in humid areas. Ask whether the iron is hot-dip galvanized, whether it is powder coated, and how the coating is applied. Ask what color options are available and whether the finish is matched across all parts of the job.

Ask how the bars are fixed and what installation includes

The strength of a security bar depends heavily on its fixings. Ask what anchors or fixing method they use for your wall type, whether the fixing points are checked, and whether the installer seals the holes against water. Clarify whether installation, removal of old bars, and cleaning up debris are part of the agreement.

Who removes old bars and waste

Ask about safety, emergency release and standards

Security bars must still allow a safe escape in an emergency. Ask how the design includes a quick release or an openable section, and how it meets fire-exit expectations for your building. For railing-type elements, the Israeli standard SI 1142 is a general reference, but exact values should always be checked with your engineer rather than assumed from a salesperson.

Ask about the timeline, approvals and who to contact

Before signing, ask how long the process takes from approval to installation, and what happens if the schedule changes. If your building has a committee, ask whether the supplier can provide drawings for their approval. Confirm who you contact after installation if something needs adjusting.

Frequently asked questions

Should I sign before the on-site measurement?

It is better not to. Wait until the measurement is done and you have approved the drawing and written specification, so the final product matches your opening exactly.

Can I ask for a sample of the finish?

Yes, asking to see a sample of the color and coating is a reasonable request. It helps you compare the look with your windows and balcony before you commit.

Do I need my building committee's approval?

Often yes, especially for balcony or facade work. Ask the supplier to provide drawings that you can share with the committee before production.

What if I want to change something after approval?

Ask how changes are handled in writing before signing. A clear process for revisions prevents misunderstandings and extra costs later.

Common mistakes to avoid

Many customers sign based only on photos and a verbal description, which leads to mismatched sizes and unclear finishes. Always get the measurement, drawing and specification in writing before approving production.

Our recommendation

Request the drawing, the material and finish details, and the fixing method in writing, and check that they match what was discussed on site. A supplier who welcomes these questions is usually one you can trust with the job.

Summary

Ask about measurement, materials, finishing, fixing, safety and timeline, and get every answer in writing before you sign. Clear answers now prevent problems during production and installation.
