Domal Interlock Profile

Q: What system size does this Domal Interlock Profile match?

It is typically matched to the 22 mm domal sliding series. If you are working on a specific system or series, your fabricator can confirm compatibility based on drawings and sample sections.

The Domal Interlock Profile is a specialised aluminium section used at the meeting point of sliding sash frames in domal-type window and door systems. It helps two sliding shutters “interlock” with each other, improving security, reducing air and water leakage, and giving the frame a neat, aligned look. Designed around the popular 22 mm domal system, this interlock profile is well suited to projects in regions with strong wind, dust or heavy rain, where reliable sealing really matters. Manufactured from Grade A aluminium alloy, the profile offers high strength with low weight, which means smooth sliding and less stress on rollers and hardware. Its multi-chamber domal design can support better insulation and, when used with appropriate gaskets and glass, contributes to improved thermal and acoustic performance. A quality coated finish helps resist corrosion and keeps windows looking fresh over years of use. With experience in aluminium profiles since 2002, Auto Tech Industry supplies Domal Interlock Profiles that maintain consistent extrusion tolerances, making fabrication, cutting and assembly more predictable for fabricators and contractors. Whether you are doing new installations or replacing older frames, this Domal Interlock Profile helps you deliver sliding systems that feel solid, close snugly and stand up well to everyday use.

Q1: What is a Domal Interlock Profile used for?

A Domal Interlock Profile is used at the meeting point of sliding window or door shutters in domal systems. It lets the two shutters interlock, improving security, reducing gaps and enhancing weather sealing.

Q2: Is this profile suitable for harsh weather conditions?

Yes. When correctly installed with suitable gaskets and glass, domal interlock profiles help reduce air, dust and water ingress, making them a good choice for areas with wind, dust or heavy rainfall.

Q3: What system size does this Domal Interlock Profile match?

It is typically matched to the 22 mm domal sliding series. If you are working on a specific system or series, your fabricator can confirm compatibility based on drawings and sample sections.

Q4: Does the profile help with energy efficiency?

On its own it is a strong aluminium interlock, but when combined with proper domal chambers, quality gaskets and insulated glass, it supports better thermal insulation and can contribute to more energy-efficient window and door assemblies.

Q5: Which surface finishes are available?

The profile is generally supplied with a protective coated finish and can be powder-coated or anodized in various colours. This improves corrosion resistance and lets you match window frames to the building’s design.

Q6: Can the Domal Interlock Profile be customized or machined?

Yes. Profiles can be cut to specific lengths and machined for locks, stoppers or additional hardware as per approved shop drawings. This helps fabricators achieve accurate, repeatable installations.
