Can retractable security gates be fitted over aluminium sliding doors?

How much do steel & aluminium security gates cost in Gauteng?

The price depends on measured dimensions, material specification, hardware, finish, access and any removal or preparation work. A written quotation confirms the full scope before work begins.

What information do you need to quote steel & aluminium security gates?

Photos and approximate measurements help with an initial discussion, but a final quote may require an on-site assessment. We confirm dimensions, access, material and finish choices, existing damage, removal work and the installation address.

How long do steel & aluminium security gates take?

Lead time depends on final measurements, material and hardware availability, finish selection and current workshop capacity. The expected manufacture and installation dates are confirmed in the written quotation rather than promised as a fixed universal timeframe.

What warranty applies to steel & aluminium security gates?

Warranty coverage varies by product, hardware, finish and type of work. The written quotation identifies the applicable manufacturer and workmanship coverage, exclusions and maintenance requirements before you approve the project.

Where in Gauteng do you provide steel & aluminium security gates?

We serve established hubs, suburbs and townships across Gauteng through scheduled site visits. Share the exact project address when enquiring so we can confirm coverage, access and appointment availability.

Do you provide steel & aluminium security gates for homes and commercial properties?

Yes. We assess houses, residential estates, complexes, shops, offices and other commercial properties. The design, specification and work plan are adapted to the property type, intended use and site-access requirements.

How do I choose the right security level for steel & aluminium security gates?

Start with the opening or boundary, likely attack points, visibility, everyday access and any estate requirements. Material thickness, spacing, locks, hinges, posts and anchoring should be specified as one system rather than judged by appearance alone.

Can steel & aluminium security gates be made to match my property?

Yes. Dimensions, layout, colour and finish can be coordinated with the property, subject to the security and structural requirements of the installation. Available options are documented with the quotation.
