Greenlogy TEC (Nantong Greenlogy TEC Electronic Technology Co., Ltd.)
FRP pultruded profiles are a composite material made with glass fiber reinforcing material as the substrate, resin as the binder, and glass fiber cloth as the covering reinforcement layer. After thorough impregnation, they are heated, formed, and cured in a metal mold, and then pultruded by a pulling machine. They have good physical properties and are widely used in high-strength and large-span applications.

Applications:
Greenlogy TEC pultruded FRP profiles are used across a wide range of applications, combining corrosion resistance, high strength, dimensional stability and light weight with thermal insulation and electrical insulation properties. Durable Greenlogy TEC profiles provide years of low-maintenance service in areas where steel, aluminum or wood components are traditionally specified. Today these profiles are commonly used in highly corrosive applications that previously required stainless steel and other costly components.

Application scenarios
Channel-section structural profiles are commonly used for load-bearing and support locations that require both strength and corrosion resistance, such as platform frames, walkway supports, equipment brackets and structural frames in corrosive environments including chemical plants and water treatment. Their cross-section facilitates combination and connection with other profiles, making them suitable for applications requiring long spans or high strength. Please confirm the specific applicable working conditions based on actual loads and environmental conditions.
Selection guidance
When selecting, it is recommended to first clarify the corrosion level of the service environment, load-bearing requirements and installation method, and then determine the cross-section specification, wall thickness and resin system accordingly; orthophthalic resin is suitable for general anti-corrosion working conditions, while highly corrosive or special media environments require separate evaluation. Listed above on this page are the channel section dimensions and unit weights, which can be used for preliminary comparison. For selection recommendations for specific projects, please contact us for detailed specifications and quotations.
Product advantages
This profile uses glass fiber as reinforcement and resin as matrix, and is formed by heated curing in a mold and continuous pultrusion. It features light weight and high strength, corrosion resistance, insulation and ease of processing, and is suitable for replacing some traditional metal profiles to reduce maintenance requirements. The surface can be covered or coated as required to suit different installation environments. Specific performance indicators are subject to the actual technical data supplied.
Inquiry guidance
For the complete specification table, weight parameters, available lengths and surface treatment options of the channel, please contact us for detailed specifications and quotations. Please provide the target cross-section dimensions, quantity, service environment and delivery requirements, and we will recommend a suitable solution accordingly and arrange further communication.
Service environment
- These pultruded FRP channel profiles are composed of glass fiber reinforcement and an orthophthalic resin matrix. The finished channels can withstand moisture and washdown in damp indoor areas, as well as rain and humid outdoor air, and will not rust like steel channels.
- Because the profile contains no steel core, the channels are suitable for chemical plants, wastewater treatment areas and coastal or offshore locations where acids, alkalis and salt-laden atmospheres attack conventional metal frames.
- As a non-conductive structural profile, the channel is used for support frames near electrical equipment, cable trays and walkway stringers, where conductive metal profiles would require separate insulation treatment.
- The glass fiber cloth reinforcement layers and the continuous pultrusion structure make it suitable both for sheltered factory interiors and for open-air structural projects; for the exact temperature, chemical exposure and load limits of a specific project, please provide application details and contact us.
Custom Cutting
Need panels that fit, or cut to shape? We custom cut FRP grating and profiles to your drawing: panels cut to size or to shape (corner cuts, cutouts), cut edges sealed with resin, and pre-cut and pre-drilled to drawing before shipping. See the custom cutting services.
