Our approach to quality rests on careful manufacturer selection, thorough assessment of technical requirements, process coordination and delivery management. Technical accuracy, transparent communication and traceability guide our work, helping us provide reliable and sustainable aluminium supply solutions.
We assess the technical and commercial requirements of each project to identify the manufacturer, production method and supply plan that best meet customer expectations.
We plan and manage each stage, from quotation through production, quality control, documentation and delivery, working closely with production partners to keep the project on schedule.
We maintain oversight of technical documents, quality records, production information and delivery progress throughout the project to provide a transparent and traceable supply process.
We aim to build long-term business partnerships by continuously improving our manufacturer network, process management and service quality in line with industry developments, technological innovations and customer feedback.
One of the core standards considered when evaluating manufacturer competence and process control capability within the quality management system.
Environmental management system standard. We consider environmental impact and adherence to sustainable production practices when assessing manufacturers.
Energy management system standard. We monitor the commitment to improving energy efficiency and systematically reducing energy consumption throughout the supply process.
Occupational health and safety management system standard. We monitor manufacturers' commitment to providing a safe and healthy working environment.
Information Security Management System. Compliance with the international standard for protecting customer and corporate data is tracked within the supply process.
An international licensing system governing powder and liquid coating quality for aluminium surfaces. It is a guarantee of coating quality.
A quality assurance licence for aluminium anodising processes. Anodic coating thickness and durability are tracked in accordance with international standards within the supply process.
Material compliance declarations and related documentation are tracked on a manufacturer and product basis within the supply process, according to customer, industry and target market requirements.
We monitor compliance with the EU REACH chemicals regulation as part of the supply process, with regard to human health and the environment.
A national certificate recognising a commitment to minimising waste in production and to environmental responsibility.
Standard for technical delivery conditions for extruded rod, tube and profile products in aluminium and aluminium alloys.
Technical delivery conditions for extruded profiles in aluminium alloys with tight tolerances. Used in architectural and structural applications.
Control of product conformity documents on a manufacturer and product basis, according to project and target market requirements, is coordinated within the supply process.
United Kingdom Conformity Assessed. A certification documenting product conformity for the UK market following Brexit.
Turkish standard for aluminium and aluminium alloy profiles. We track product quality in the supply process for domestic construction and industrial applications.
