Commercial Vehicles

We design and produce an endless variety of fiberglass parts for trucks, buses, construction machinery, agricultural vehicles, motorcycles, boats, as well as special purpose machinery.

Coaches and City Buses

We manufacture outer body parts in the form of large-format fiber-reinforced duroplastic parts and polyurethane components for the coach interiors.


C.F. Maier manufactures both interior and exterior paneling for trucks with a high surface quality using the robust and weather-resistant GRP material.

Construction Machinery

For construction machinery, C.F. Maier manufactures components for the exterior paneling in the form of large-scale fiber-reinforced polyester parts and molded polyurethane parts for the interior.

Agricultural Machinery

C.F. Maier manufactures robust outer body parts for agricultural machinery using GRP – a material with is both age- and weather-resistant. We produce linings for the interior using foamed PUR.

Special-Purpose Vehicles

C.F. Maier manufactures plastic outer body parts and interior paneling for various special vehicles such as forklifts, ambulances, snowcats, and more.

We manufacture exterior parts in particular from glass-fiber-reinforced plastic. This makes it easy to form ribbing on the inside. Fastening elements can also be pressed in. The process allows the tightest dimensional tolerances to be maintained. We implement smaller quantities by wet pressing or hand laminating.

An important advantage of GRP is its low weight. The use of GRP parts in buses helps to save fuel, increase the payload and improve the driving characteristics. Examples of the components we produce include vehicle fronts, A-pillar cladding, tailgates, bumpers, wheel arches, bumpers, spoilers, and headlight flaps.

C.F. Maier manufactures exterior cladding for trucks. The material glass fiber reinforced plastic offers many advantages for this: The parts are resilient, durable, corrosion-resistant and insensitive to weathering as well as road salt and dirt. GRP is therefore ideally suited for the punishing conditions that long truck journeys sometimes present.

The properties of glass-fiber-reinforced plastic are particularly beneficial for vehicles that are subject to heavy wear and tear, such as construction machinery: GRP is resistant to rust, temperature, weathering and ageing, and is also lightweight, impact-resistant, easy to install and cost-effective. Compared with alternative cover parts or cladding made of sheet steel, the use of plastic thus offers numerous advantages. The addition of a gelcoat layer, also available in two colors on request, also creates high-quality surfaces that no longer require repainting.

Mobile Homes

Outer body parts for mobile homes are one of C.F. Maier’s main production areas. We manufacture vehicle front caps, sidewalls, panels, engine hoods, roofs, and much more.

The components are mainly made of polyurethane foam – and some are fiber-reinforced. This material allows for a weight reduction of up to 40 percent when compared to other plastics – without any loss of stability.

The sandwiched construction with a PUR foam core also is advantageous because cables, hoses, pipes, furniture anchors, and other wood, metal, or plastic elements can be embedded in the component and are therefore not visible later.

C.F. Maier brings around 35 years of experience in the field of motor home roofs to the table. Under the SCA brand, we produce and sell high-quality pop-up roofs and roof extensions for a number of brands and vehicles.
