Glass fiber reinforced polyurethane pultruded profiles have achieved large-scale commercial landing in six core fields, solving long-term pain points of traditional profiles in each industry:

2.1 Passive & Energy-saving Building Door and Window System

This is the most mature application field of glass fiber reinforced polyurethane thermal break profiles. Aluminum thermal break profiles have poor overall insulation, while wood profiles have short outdoor service life. Lovely House customized glass fiber reinforced polyurethane window frame profiles adopt mixed-layer glass fiber structure, with thermal conductivity below 0.23 W/(m·K), greatly reducing building heating and cooling energy consumption. Supporting personalized section mold opening, color coating and anti-aging surface treatment, Lovely House GFR-PU(FRPU/GRPU) building profiles match high-end passive house, prefabricated villa and green public building construction standards.

2.2 New Energy Photovoltaic & Wind Power Auxiliary Structure

Coastal distributed photovoltaic power stations, offshore wind power auxiliary brackets face severe salt fog corrosion all year round. Hot-dip galvanized steel brackets need annual anti-rust maintenance with high later cost. Lovely House anti-corrosion glass fiber reinforced polyurethane pultruded support profiles feature 50-year outdoor service life without maintenance, lightweight structure to reduce foundation bearing pressure, and customized hole position integrated molding to simplify on-site installation. It is the mainstream optimized material for new energy outdoor support components in 2026.

2.3 Chemical Plant & Marine Industrial Frame Profiles

For chemical workshop partition frames, offshore platform handrails, sewage tank edge frames, ordinary polyester fiberglass profiles are easy to delaminate and bubble under long-term chemical erosion. Relying on self-built material laboratory, Lovely House optimizes fiber-resin interface bonding technology for glass fiber reinforced polyurethane materials, improving medium corrosion resistance comprehensively. The factory can produce heavy-duty anti-corrosion GFR-PU(FRPU/GRPU) profiles in batches, with stable structural strength under cyclic chemical erosion.

2.4 Rail Transit & Municipal Public Facilities

Urban walkway handrails, subway non-load-bearing partition profiles, municipal landscape guardrails require flame retardant, anti-aging and low-maintenance materials. Lovely House flame-retardant modified glass fiber reinforced polyurethane pultruded profiles reach B1/A flame retardant grade, no toxic smoke combustion, meeting municipal public safety standards. Compared with PVC profiles prone to aging and embrittlement, Lovely House GFR-PU municipal profiles reduce replacement frequency by more than 70%.

2.5 Cold Chain Warehouse & Low-temperature Workshop Structural Components

Metal profiles are easy to condense water in constant-temperature low-temperature warehouses, causing wall panel damage and energy loss. Glass fiber reinforced polyurethane pultruded insulation profiles produced by Lovely House avoid condensation completely, with stable mechanical performance under -40℃ low temperature, no brittle cracking, specially developed for cold chain enclosure keel and connecting profile supporting use.

2.6 Special Customized Industrial Irregular Profiles

Many industries need non-standard special-shaped composite profiles with small batch and diversified specifications. Benefiting from flexible automated pultrusion production line and independent mold workshop, Lovely House provides fast customized service for special-shaped glass fiber reinforced polyurethane pultruded profiles, completing drawing confirmation, mold development,covering smart equipment shell, agricultural greenhouse anti-corrosion keel, logistics equipment reinforcing profile customized production.
