Heavy duty lorry side curtain parts for UK haulage
Heavy duty lorry side curtain parts are structural plastic extrusions designed to maintain the aerodynamic integrity of curtain sided trucks. These components include critical items such as pelmets and Kedar cord which secure the vehicle load.
Abbey Extrusions was established in 1985 to provide the technical expertise required for the UK transport environment. Our components are durable enough to withstand 70mph wind loads without losing their profile shape.
A primary challenge for hauliers is material fatigue in components exposed to -20°C winter temperatures. Standard plastics often become brittle and crack when subjected to these extreme thermal stresses on the road.
As a specialist curtainsider pelmet section supplier UK, we provide a solution through precision-extruded profiles. These maintain structural integrity across diverse thermal ranges with tolerances of +/- 0.05mm.
Experience since 1985 shows that inferior plastics fail when subjected to high-pressure cleaning systems. We advocate for high-grade thermoplastics that resist pressures up to 50 bar during routine fleet maintenance.
We utilise advanced tooling to create bespoke profiles that meet unique fleet requirements. This precision ensures that every component integrates seamlessly with existing trailer hardware and tracks.
The role of curtainsider pelmet sections
The pelmet acts as a flexible weather seal mounted to the top rail of the trailer system.
We manufacture these seals from Flexible PVC with a specific 75 Shore A hardness to prevent water ingress. This material remains resilient whilst protecting the internal cargo from driving rain and road spray.
Best practice requires the inclusion of UV stabilisers to prevent the material from undergoing a Shore D transition. Without these additives, the plastic becomes brittle and fails during routine operation in direct sunlight.
Understanding Kedar cord in trailer systems
Kedar cord serves as the primary anchoring bead that secures curtain fabrics into the aluminium track.
We specialise in producing Kedar cord in diameters from 3mm to 15mm to suit standard UK trailer systems. This range ensures a consistent fit across the entire 13.6-metre length of a standard trailer.
Our manufacturing process creates low-friction surfaces to facilitate smooth curtain movement. This reduces the physical effort required during frequent loading operations and prevents snagging in the track.

Engineering specifications for curtainsider pelmet sections
We manufacture Flexible PVC pelmets to achieve a 200% elongation at break. This elasticity prevents material failure during extreme curtain tensioning on the road.
Durable profiles require a wall thickness between 3mm and 5mm to resist tearing. This specific thickness provides the structural mass needed for long-term use in heavy haulage.
As a leading curtainsider pelmet section supplier UK, we maintain tolerances of +/- 0.05mm. These tight limits eliminate rattling and air gaps at speeds of 60mph.
In our view, co-extrusion is the most effective method for high-performance profiles. We combine rigid and flexible materials in a single profile to enhance mounting stability.
This dual-material approach ensures the mounting base remains firm whilst the sealing fin stays flexible. Compliance with UK haulage safety standards requires such technical precision for load security.
As UK extrusion specialists, we advocate for profiles that integrate seamlessly with trailer tracks. Our Leicestershire facility, established in 1985, produces these components to exacting standards.
Material properties of Flexible PVC
Flexible PVC is the primary thermoplastic used for high-performance vehicle seals.
It offers excellent chemical resistance to road salts and diesel spills. This resistance prevents surface degradation during thousands of miles of motorway travel.
Experience since 1985 shows that cold-crack resistance is essential for UK operations. Our formulations ensure performance at temperatures down to -30°C.
This versatile material is available in ID sizes from 3mm to 75mm for various trailer applications. We ensure the material maintains a 75 Shore A hardness for optimal sealing performance.
Standard versus bespoke pelmet profiles
Bespoke engineering allows for profile designs that standard off-the-shelf solutions cannot match.
Standard 100mm heights are common, but we often produce 150mm industrial versions. These larger profiles are necessary for specialised trailers with deeper top rails.
We offer bespoke curtainsider pelmet sections for custom fleet orders. You can contact our technical team to review your specific tooling requirements for non-standard trailer designs.

Material durability in HGV side curtain components
Material selection determines the long-term reliability of curtain anchoring systems. We contrast the performance of Nylon 6 and Nylon 12 to ensure components withstand the mechanical stresses of the UK haulage network.
As a specialist curtainsider pelmet section supplier UK, we advocate for Nylon 12 due to its low moisture absorption rate of 0.2%. This prevents the material from swelling or losing its +/- 0.05mm tolerance in damp British weather.
Experience since 1985 shows that Nylon 6 can absorb up to 9% moisture. This leads to dimensional warping that compromises the fitment of internal support profiles over time.
Rigid support profiles often require a Shore D hardness of 80. This ensures the component remains stiff enough to provide structural bracing under heavy wind loads.
We also utilise Polyurethane (PU) for components that require high abrasion resistance. This material is resilient enough to endure thousands of curtain cycles without significant surface wear.
Nylon 12 for high stress components
Nylon 12 provides superior engineering advantages in both fluid and mechanical haulage systems.
We utilise precision extrusions with a tensile strength of 50 MPa to prevent warping. This high strength ensures that anchoring beads do not pull out of the aluminium track during high-speed transit.
You can read our detailed guide on nylon tubing for more technical context on polymer performance. Our expertise in this material allows us to produce bespoke profiles that maintain their shape in demanding environments.
Polyurethane and impact resistance
Polyurethane (PU) serves as an essential material for vibration damping within heavy-duty trailers.
We produce components with a Shore A rating of 90 for high-impact curtain rollers and guides. This specific hardness allows the material to absorb shocks without fracturing or permanent deformation.
We also supply Polyurethane tube as a reliable pneumatic component for automated curtain systems. These tubes withstand pressures up to 50 bar whilst maintaining a tight bend radius of 25mm for compact installations.

Best practice for sourcing bespoke extrusion profiles
As UK extrusion specialists, we advocate for a structured approach when commissioning custom components for legacy fleets. We guide partners through the engineering process from initial concept to final production.
Commissioning bespoke plastic extrusion tooling requires precise technical drawings with +/- 0.05mm tolerances to ensure aerodynamic performance. In our view, our ID range from 3mm to 75mm accommodates the vast majority of UK trailer specifications.
Sourcing from a curtainsider pelmet section supplier UK allows for rapid prototyping and physical sample verification. This local proximity ensures that material compatibility with existing PVC curtain fabrics is confirmed during technical consultations.
Our Leicestershire facility has provided these tailored requirements since 1985 to reduce lead times for major haulage contractors. We ensure every profile maintains a Shore A hardness of 75 to provide consistent sealing across the entire fleet.
Technical drawings and tolerances
Precision engineering is the foundation of reliable trailer component design with a Shore A hardness of 75.
We maintain a tolerance of +/- 0.05mm to ensure perfect fitment with Kedar cord channels. Sample runs allow our technicians to verify material performance and dimensional accuracy before proceeding to full production.
Best practice dictates that Shore hardness should be tested at 20°C to simulate standard operating conditions. This verification step prevents the installation of parts that may fail under the mechanical stress of 70mph motorway speeds.
Reducing fleet downtime with quality parts
High-quality component sourcing has a direct positive impact on haulage company profit margins.
Experience since 1985 shows that durable parts rated for 50 bar pressure reduce annual maintenance costs by 15%. These high-performance profiles resist the environmental degradation caused by UK road salts and UV exposure.
We also provide tube forming services for custom structural supports used in specialised haulage trailers. Using components that meet these technical standards ensures your fleet remains compliant with UK haulage safety standards.
