Mazuli

Mazuli, aluminium joinery manufacturer in Leeds

Mazuli is a British manufacturer of aluminium doors and windows established in Leeds (West Yorkshire). The company presents itself as an accredited supplier of Cortizo systems and as one of the largest distributors of this European manufacturer in the UK. Its activity combines in-house manufacturing with direct delivery to site, for both trade professionals and retail customers.

Origin and evolution of the company

The company was founded in 2020 with the aim of offering trade professionals access to high-end aluminium joinery with short lead times and transparent pricing. It began operating from a single unit in Leeds and gradually expanded its client base among builders, architects and contractors. In 2023, growing demand led to the opening of a new factory on Westgate Link, while the original Gelderd Road unit became a dedicated warehouse.

Facilities and manufacturing capacity

The main plant, located on Westgate Link, covers 25,000 square feet and houses the cutting, fabrication, assembly and final quality control processes. The 9,000 square foot Gelderd Road warehouse holds stock for rapid dispatch. The company states that it fully controls the supply chain, with no middlemen, which allows it to adjust lead times and maintain its quality standards.

Mazuli's catalogue is organised around aluminium solutions for openings and enclosures:

Lead times and logistics

The company manages delivery with its own fleet, without using external couriers, and delivers throughout mainland Great Britain. For Northern Ireland and the islands, shipping is to the connecting port. The lead times stated on the site are 2 to 5 working days for unglazed products in standard colours, 6 to 10 working days for glazed products in standard colours, two weeks for RAL finishes and four to six weeks for woodgrain finishes. These lead times are subject to order quantity.

Purchasing process

The workflow described by the company consists of three steps: the customer sends drawings or specifications and receives a quote within 24 hours; once the order is approved, manufacturing takes place at the Leeds plant using Cortizo systems and a delivery date is agreed; finally, the order is delivered on the agreed date using the company's own fleet.

Accreditations and certifications

Mazuli describes itself as a certified Cortizo manufacturer and a fully accredited supplier of this range. The profiles used are tested in national and international laboratories for water tightness, air permeability and wind resistance. The company also holds QUALICOAT certification for architectural aluminium powder coatings; QUALIDECO for decorative coatings; and SEA-SIDE, certification of enhanced corrosion protection in coastal and marine environments.
