Fiberglass Pultruded Sign Post

Product Introduction

Pultruded profiles are made using the pultrusion process. Pultrusion is a continuous production method for glass fiber reinforced plastic profiles with uniform cross-sectional shapes and dimensions. The process involves: under the traction force produced by the forming equipment, adding materials (such as glass fiber roving, glass fiber mat, etc.) which are impregnated with matrix materials (such as unsaturated polyester resin, etc.) according to a specific configuration, then passing through a mold system where they continuously cure and form, resulting in a continuous output of smooth-surfaced, dimensionally stable, and extremely strong glass fiber reinforced plastic profiles. The main applications of pultruded profiles include: insulating support components, urban rail three-track protective covers and supports, antenna poles, high-voltage cable trays, high-voltage power operation rods, generator radiators, stairs and handrails, operating platforms, corridors, oil storage tanks, distribution boards and distribution rooms, drainage systems, berths and underwater identification markers, pressure rods in trains and cars, corner plates, highway guardrails, sound-absorbing panels, anti-glare panels, filler supports in towers, filter plate supports, frame materials for cold storage, etc.

Core Strengths 

1.Resistant to corrosion and rusting, it shows no corrosion in acidic, alkaline, salt spray or damp underground environments. Its service life can exceed 30 years.  
2. It is non-conductive and does not pose any risk of electricity leakage or lightning strike. Thus, it is safer for use in power and communication scenarios.  
3. Lightweight and highly strong, its weight is only 1/10 that of cement piles. Transportation and installation do not require large equipment, and the construction is very convenient.  
4. The identification is clear. The text and patterns can be integrated into one piece. It is resistant to wear and does not fade. Even after long-term outdoor use, the identification remains clearly visible.  
5. Anti-theft measures, with no recycling value, effectively eliminating the risk of theft at its source. 

Structural Characteristics 

It is made through continuous glass fiber pultrusion molding, with an overall dense structure without any layering or bubbles, and excellent sealing performance. It mostly adopts solid/hollow structures of square tubes and circular tubes. The wall thickness is uniform. It can be customized for height, specifications, and color as per requirements. The identification text can be produced by laser engraving, screen printing, or integrated molding. The bottom of the pile body can be customized with pre-buried, flange, etc. installation structures. The overall structure is resistant to impact and settlement, and will not deform or be damaged during long-term use. 

Focusing on Performance 

Main features include anti-corrosion, weather resistance, insulation safety, durable marking, and theft prevention. 
It is suitable for underground installation, long-term outdoor use, and harsh corrosive environments. It maintains stable performance within a wide temperature range, and is resistant to aging, impact, and wear. It meets the long-term stable usage requirements for various pipeline markings and warnings. 

 Applicable Scenarios 

It is widely used in various industrial and municipal scenarios where there is a need for identification, warning, and corrosion prevention, such as power cable identification posts, communication pipeline identification posts, gas pipeline warning posts, oil pipeline marking posts, water conservancy boundary posts, municipal road warning posts, scenic area boundary posts, and mining identification posts.
