Greenhouse Aluminium Profiles & Plastic Extrusions UK

WE PROVIDE GREENHOUSE PROFILES FOR REPEATABLE BUILDS

Greenhouse systems need materials that can withstand environmental exposure while supporting structural performance, glazing retention and ventilation. Aluminium greenhouse extrusions are widely used for greenhouse frames because they combine strength, weather resistance and the ability to support glass and polycarbonate panels. Plastic greenhouse profiles are commonly used for glazing panels and trims, irrigation tubing and flexible connectors, offering lightweight, reliable and cost-effective solutions across greenhouse systems.

Here at BWC Profiles, we supply greenhouse extrusion profiles that do more than meet a specification. Our solutions are designed to support efficient manufacturing, straightforward installation and reliable long-term performance. Whether you need aluminium greenhouse frame extrusions or plastic profiles for greenhouse systems, we can help you find the right solution for your build.

We know Greenhouse extrusions play a vital role in the strength, performance and longevity of modern greenhouse systems. Used across framing, glazing, ventilation and weather protection, these profiles help create greenhouse structures that are easier to assemble, more secure in use and built to last.

Aluminium greenhouse extrusions are ideal for greenhouse frames thanks to their high strength, weather resistance and dependable support for glass and polycarbonate glazing panels. Plastic greenhouse profiles offer lightweight, versatile and cost-effective solutions for glazing trims, connectors, tubing and other functional greenhouse components.

Extrusion is used in greenhouse systems because it allows multiple functional requirements to be built into a single section. Instead of adding separate components to create support, location, sealing or weathering features, those details can be designed directly into the profile.

That makes extrusion a practical choice for greenhouse frames, glazing bars and related sections where profile geometry needs to support both structural performance and interface requirements. It helps reduce reliance on secondary parts and allows more of the assembly function to be carried within the section itself.

For greenhouse manufacturers, that creates a more efficient route to profiles designed around the needs of the finished system rather than relying on added parts to solve those requirements later.

Typical Greenhouse Applications

Greenhouse systems rely on multiple components working together to deliver strength, efficiency and long-term performance. Framing, glazing, joints and opening elements must all integrate smoothly, which is why extrusion plays such an important role in greenhouse design and manufacture. Where profile geometry needs to support structure, glazing and straightforward installation within one assembly, the right extrusion solution adds real value.

We supply aluminium greenhouse extrusions and plastic greenhouse profiles for a wide range of greenhouse applications, helping manufacturers and system builders achieve reliable performance, practical assembly and consistent product quality.

Common greenhouse extrusion applications include:

Main structural frames
Aluminium greenhouse extrusions are widely used for uprights, rafters, cross-members and structural frame sections, providing the strength and durability needed for dependable greenhouse construction.

Glazing bars and glazing capture profiles
Extruded profiles help secure glass and polycarbonate panels in both roof and side assemblies, supporting safe panel retention, accurate fitting and efficient installation.

Roof vents, side vents and opening mechanisms
Greenhouse extrusion profiles are used in ventilation systems to support opening sections that improve airflow, temperature control and growing conditions.

Door tracks, guides and hardware carriers
Extrusions can also be designed for door systems and moving parts, helping create smooth operation, secure positioning and reliable performance over time.

Gutters, drip edges and drainage paths
Well-designed greenhouse profiles support water management, helping to guide rainwater away effectively and protect the structure from unnecessary exposure.

Shading and screening carriers, clip rails and support sections
Extruded profiles are ideal for integrating shading, screening and internal support features, allowing greenhouse systems to be adapted for practical day-to-day use.

Protective trims, glazing gaskets, insulating spacers and cover profiles in plastic
Plastic greenhouse profiles provide lightweight, cost-effective solutions for a range of finishing and functional components, helping improve fit, protection and thermal performance across the full system.

Why this matters

Choosing the right greenhouse extrusion profiles can improve more than just structural integrity. It can also help reduce assembly time, improve glazing support, support ventilation performance and deliver a more reliable finished greenhouse system.

Working with customers, BWC Profiles manage and produces aluminium and plastic extrusion solutions for greenhouse applications that are built around performance, ease of installation and long-term value.

MACHINING STRATEGY

Extrusion should provide the main profile geometry efficiently, with machining used only where tighter control is needed for assembly, hardware location or joint preparation. The aim is a controlled route, not unnecessary secondary work.

Typical machining operations include:

Drilled and tapped holes for fixings and hardware
Slots and cut-outs for vents, hinges and access details
End machining for joint closure and connection points
Reference faces for repeat fixturing and measurement
Localised machining where fit or alignment depends on it

Surface Protection

Greenhouse components often need finishing for outdoor use, appearance or added protection. That needs to be planned with the profile design so the finish does not interfere with fit, assembly or how parts come together.

Key considerations include:

How finishing affects mating or locating surfaces
Masking where controlled fit or contact is needed
Protection of visible or functional surfaces during handling
Packaging that helps parts arrive in usable condition
