WE SHAPE ALUMINIUM. YOU SHAPE THE FUTURE.

Your custom aluminium profiles, carefully designed together and extruded, machined and finished with precision - from De Lier (NL) since 1974.

Discuss your project Our capabilities

From idea to profile

Turn your requirements into a profile that works in practice.

Expertise across industries

Aluminium profiles tailored to your application and production process.

With care for the future

Recycled and low-carbon aluminium options to help reduce your profile’s CO₂e footprint.

FROM IDEA TO PROFILE

Together, we make it happen

our application determines what an aluminium profile needs to do. That is why we work with you from the initial idea or first drawing, considering function, design, manufacturability, material choice and production.

From De Lier, we turn your requirements into a profile that not only works on paper but also performs reliably in practice. We combine over 50 years of aluminium expertise with precision extrusion and carefully coordinated machining and finishing through established partners. This ensures that technical choices, quality, planning and the final result are properly aligned.

More about us

custom aluminium profiles

A custom aluminium profile requires the right choices in design, extrusion, machining and material. We align these choices with your application, production process and sustainability ambitions. The result is a profile that can be manufactured efficiently and performs reliably in practice.

From technical requirement to manufacturable profile

Together, we translate your idea and technical requirements into an aluminium profile that brings together form, function and manufacturability.

more information

Extruded to your specifications

We extrude your aluminium profile with a focus on dimensional accuracy, surface quality and repeatability.

more information

Machined for your application

From sawing, drilling and milling to anodising: every machining and finishing process is tailored to your application.

More information

low carbon aluminium

Choose low-carbon aluminium produced using renewable energy to reduce your profile’s CO₂e footprint.

More information

Recycled aluminium

Choose aluminium with at least 65% recycled content to reduce the use of primary raw materials.

More information

Aluminium solutions in practice

"We know exactly what to expect from each other, which means we achieve very short lead times with new developments and the first production runs are immediately usable."

what our customers say about us

Aluminium profiles for your application

From load-bearing capacity and dimensional accuracy to weight reduction and heat dissipation, every application places different demands on aluminium. Discover what custom aluminium profiles can make possible in construction, greenhouse horticulture, transport, solar and electrical engineering.

Building & construction

Aluminium profiles for façades, window frames and other building systems, tailored to strength, dimensional accuracy and design requirements. With material options that can support your ambitions for circular and sustainable construction.

More information

Solar

How sustainable is solar if the infrastructure around it fails to keep pace? Make a conscious choice with lightweight, strong and weather-resistant custom aluminium profiles — with the option of low-carbon aluminium or aluminium with a high recycled content.

More information

Transport

Looking to move forward in transport manufacturing? Smart aluminium profiles can make vehicle bodies, load beds, trailers and vehicle interiors lighter and easier to assemble. Extruded to your specifications for strength, dimensional accuracy, length and repeatability.

More information

Greenhouse construction

How do you combine strength with minimal light obstruction? With robust aluminium profiles and intelligent geometries for greenhouse roofs, façades and ventilation windows, tailored to your requirements. We also extrude custom aluminium profiles for transport systems, growing tables, lighting systems and growing gutters.

More information

Electrical

Aluminium profiles for LED lighting, enclosures and cable management systems, tailored to your requirements for heat dissipation, electrical conductivity, dimensional accuracy and assembly.

LOWER CO₂e STARTS WITH CONSCIOUS CHOICES

A lower CO₂e footprint requires conscious choices in materials, production and logistics. That is why we use energy and raw materials as efficiently as possible, reduce waste streams and organise transport intelligently.

We also offer aluminium produced using 100% renewable energy and aluminium with at least 65% recycled content. Material options that can help you reduce the CO₂e footprint of your aluminium profile.

  • Informed material choices Choose low-carbon or recycled aluminium that meets your technical requirements and sustainability ambitions.

  • More efficient production We optimise our processes to use energy and materials as efficiently as possible.

  • Less waste We reduce waste streams and aim to recover residual materials in the most effective way possible.

  • Smarter transport Short supply chains and efficiently coordinated logistics help reduce unnecessary transport movements.

Our ISO 14001-certified environmental management system helps us systematically measure, manage and reduce our environmental impact.

Read more about sustainability

Consistent quality, run after run

Your aluminium profile must meet the agreed specifications in every production run. That is why we monitor quality throughout the entire process: from the material and die to extrusion and final inspection. Our certifications for quality management (ISO 9001), environmental management (ISO 14001) and occupational health and safety (ISO 45001) support controlled and responsible operations. In this way, we work continuously to deliver repeatable quality, reduce our environmental impact and maintain a safe working environment.
