SPARE was established in May 1995. Since its inception, the company has focused on the development and production of FRP pultruded and moulded products.

Industry standards

SPARE is the industry benchmark for pultruded fiber reinforced polymer (FRP) structural profiles.

Structural optimization

In many applications, fiberglass structural profiles offer significant advantages over steel, wood and concrete.

Pultrusion Power

SPARE has the one of the largest pultrusion capacity and product size capability in the world with more than 50,000 sq. ft. of space to house over 55 pultrusion machines in three facilities in China.

Process Description

FRP Structural Shapes

The FRP structure is made of pultruded FRP rectangle/square tubes, FRP channels profiles, FRP plates, etc.  SPARE offers FRP profiles to the cooling tower industry for 20+ years without a tower collapse so far.

Process Description


The features of SPARE’s FRP products offer significant benefits in many architectural applications such as bay windows, fencing systems, blinds & brackets, wall connector, etc. 


FRP profiles are widely used in construction, automobile, photovoltaic, electric power, chemical and other industries.

Corrosion resistant

Fiber reinforced polymer (FRP) composites offer reliable resistance to a wide range of chemicals and harsh environments.

Flame retardant

Fiber reinforced polymer (FRP) composites can reach UL94-V0 level flame retardant by testing through vertical testing method.

Strength - Weight

Fiber reinforced polymer (FRP) composites are stronger than steel in the lengthwise direction, but lighter in weight.

Maintenance Fee

Fiber reinforced polymer (FRP) composites are durable and resistant to impact/corrosion/rot, eliminating the need for constant maintenance.

Flexible Design

Fiber reinforced polymer (FRP) composites are highly designable. Factors such as shape, color, size and functional features can be customized.

Easy and Fast Installation

Fiber reinforced polymer (FRP) composites are ideal for projects that have tight timelines. Less specialists and equipment are needed for installation compare to steels.


Our Recent Work

Spare’s range of profiles is extensive, encompassing both standard shapes like Square Tube, Channel, Angle, I-beam, Round Tube, Panel, and Rectangular Tube, as well as larger profiles such as Plank, Blade, and Deck. The company also welcomes special requests and customization to meet unique needs.
