FiberrGuard™ FRP Guardrail Systems
Modular, corrosion-resistant fiberglass guardrail systems for industrial and infrastructure applications
Technical Overview
FiberrGuard FRP guardrail systems are manufactured from fiberglass-reinforced plastic composites for industrial, infrastructure, marine, utility, wastewater, and corrosive environments.
The system combines pultruded structural profiles with molded connection components to provide long service life, high strength-to-weight performance, electrical non-conductivity, and minimal maintenance.
Pigments are integrated into the resin during manufacturing, producing self-colored profiles that do not require routine painting or coating for corrosion protection.
Typical Applications
FiberrGuard systems are commonly used where corrosion resistance, electrical insulation, environmental durability, and reduced maintenance are required. Compared with conventional metal systems, FRP does not rust and does not depend on periodic repainting for corrosion protection.
Industrial Platforms and Walkways
Durable fall protection for areas exposed to moisture, chemicals,
weather, and frequent use.
Wastewater Treatment Facilities
Suitable for continuously wet and corrosive environments where
conventional steel systems may deteriorate rapidly.
Chemical Processing Plants
Resists chemical exposure and corrosive vapors while reducing coating
and maintenance requirements.
Cooling Towers
Appropriate for high-moisture and UV-exposed environments where
corrosion resistance and electrical insulation are advantageous.
Power Generation Facilities
Used where nonconductivity and corrosion resistance support worker
safety and long-term reliability.
Marine and Coastal Environments
Withstands salt air, humidity, and moisture without rusting or flaking
protective coatings.
Mezzanines, Stairs and Access Ways
Lightweight components simplify handling and installation for indoor
and outdoor elevated work areas.
Oil, Gas and Process Facilities
Provides modular fall protection for platforms and access structures
exposed to weather and aggressive industrial conditions.

Guardrail System Components
FiberrGuard systems are assembled from modular pultruded profiles and molded connection components designed for consistent fit and efficient installation. Component selection depends on the railing layout, mounting method, stair geometry, kick-plate requirements, and project specifications.

OSHA Guardrail Requirements
The following overview summarizes principal OSHA dimensional and load criteria relevant to industrial platforms, walkways, mezzanines, stairs, and elevated work areas under 29 CFR 1910.28 and 1910.29.
Guardrail Height
Top rails are generally positioned 42 in above the walking or working
surface, plus or minus 3 in.
Top-Rail Load
The top rail must withstand a concentrated load of at least 200 lb
applied in an outward or downward direction.
Intermediate Members
Midrails and comparable intermediate members must resist a concentrated
load of at least 150 lb applied in any downward or outward direction.
Midrails and Opening Control
Midrails are positioned approximately halfway between the top rail and
walking surface. Openings are controlled to prevent passage of a
19-inch-diameter sphere.
Toe Boards and Kick Plates
Where falling-object protection is required, toe boards must extend at
least 3.5 in above the walking surface.
Material Acceptance
OSHA does not prescribe a specific guardrail material. FRP can be used
when the completed system satisfies applicable dimensional, strength,
surface, and installation requirements.
Compliance note: FiberrGuard systems are intended to
satisfy applicable dimensional and load requirements when properly
designed, configured, anchored, installed, inspected, and maintained.
Final compliance with OSHA requirements, local building codes,
engineering documents, and project specifications remains the
responsibility of the system designer, installer, contractor, and site
owner.
General guidance only: Dimensions, weights, mechanical
properties, resin formulations, reinforcement configurations, colors,
fire-retardant performance, UV protection, hardware, anchors, spacing, and
system capacity may vary by product configuration and project
requirements. Component-level material values are not complete guardrail
system design capacities. Post spacing, base-plate anchorage, substrate
strength, connection detailing, stair geometry, field fabrication,
environmental exposure, and applied loads must be evaluated for the
specific installation.
