Crittall Steel Services


Our Process

1. Contact & Design Stage

At KJA Services, we understand that the contact and design stage is crucial when ordering your chosen Crittall product. During this stage, our team of experts will work closely with you to determine your exact requirements and ensure that your vision is transformed into a tangible design that is not only aesthetically pleasing but also meets your functional requirements. We will measure and assess the opening and work with you to find the best solution that is both practical and aesthetically pleasing. Once the design is approved, we will provide you with a detailed quote, drawing and timeline. At KJA Services, we strive to make the contact and design stage a hassle-free and collaborative experience, ensuring that your bespoke Crittall product is delivered on time and to your complete satisfaction.

2. Manufacturing Stage

During the manufacturing stage of ordering your chosen Crittall product, skilled craftsmen and technicians work diligently to transform raw materials into high-quality doors, screens and windows. The process begins with the careful selection of high-grade steel, which is then shaped and cut to precise measurements by skilled metalworkers. The steel sections are then assembled and welded together, creating a durable frame that can withstand the test of time due to its galvanised and polyester powder-coated finish. The frame is then sent through a rigorous quality control process to ensure that every component meets the manufacturer's strict standards. With years of experience and ingrained attention to detail, Crittall's manufacturing process produces doors, screens and windows that are both beautiful and functional.

3. Installation Stage

The installation stage is a crucial part of achieving your dream Crittall product. This is the time when the design and planning all come together to create the final product. It requires careful attention to detail, as even small mistakes can have a significant impact on the functionality and aesthetic of the end result. During this stage, the installation team will work closely with you to ensure that your expectations are met and that the final product is installed safely and securely. It’s important to choose a reputable and experienced installation team and we ensure that the installation is done correctly and efficiently. Once the installation is complete, you’ll be able to enjoy your newly installed Crittall product and all the benefits it provides.
