Fiberglass Handrail and Guardrail Systems

Industrial FRP handrail systems in square- and round-tube configurations, with posts, top and middle rails, kick plates, splices, molded fittings and base options. Manual-verified nominal specifications are separated from the project load, connection and anchor design.

Complete Edge-Protection Assemblies

Specify the rail, post, fitting, kick plate and base as one system

A fiberglass railing is not qualified by a tube size alone. The finished assembly transfers top-rail and intermediate-member loads through posts, splices, corner fittings, bases, anchors and the supporting substrate. F1 therefore keeps the catalog geometry visible while making the project load basis and release drawing explicit.

This page owns the industrial handrail and guardrail intent. For vertical access, use the separate fiberglass fixed ladder systems page; for raw profile stock, use the round- and square-tube pages.

Manual-Verified Specifications

Square and round FRP handrail system specifications

The source tables are rebuilt below as accessible, supplier-neutral HTML. Suspect or internally conflicting fields are not silently corrected; they are withheld or carried into a release note until an approved BOM resolves them.

Square system

Square-tube FRP handrail system

A rectilinear post-and-rail arrangement with internal splices, kick plate, corner fittings and an optional base detail.

Component	Nominal catalog value
Post spacing	1,500 mm maximum
Handrail height	1,220 mm maximum
Top rail	Square tube 50 × 50 × 6.4 mm
Middle rail	Square tube 50 × 50 × 6.4 mm
Insert splice	Square tube 38 × 38 × 6.4 mm
Kick plate	100 × 14 × 3 mm
Kick-plate splice plate	45 mm wide × 101 mm long × 6 mm thick
90° kick-plate splice angle	54 × 29 × 6.4 mm
90° handrail fitting	3 × FRP angles, 152 × 152 × 13 mm; 38 mm long
Adjustable fitting	Plastic fitting, 39°–180°
Catalog connection rivet	4 × 20 mm

Release note: The source illustration and table disagree on part of the middle-rail geometry. The approved project BOM and connection drawing therefore control the released assembly.

Round system

Round-tube FRP handrail system

A round post-and-rail arrangement using molded elbow, tee, cross and foot-base fittings with a separate kick plate.

Component	Nominal catalog value
Post spacing	1,500 mm maximum
Handrail height	1,220 mm maximum
Post	Round tube 50 × 5 mm (catalog notation)
Top rail	Round tube 50 × 5 mm (catalog notation)
Middle rail	Round tube 50 × 5 mm (catalog notation)
Kick plate	101 × 14 × 3 mm
Fittings	BMC elbow, tee, cross and foot base
Catalog fitting screws	M5 × 55; elbow 2, tee 2, cross 3
Catalog foot-base anchors	M6 × 90; two per foot base

Release note: A kick-plate splice length in the source table appears anomalous and is intentionally omitted. Final splice size, fastener material and anchorage come from the approved project drawing.

Square-System Connections

Internal splices, corners and kick-plate details

Square fiberglass handrail system connection concept with splices, corner details, kick plate and optional base — Manual-derived connection concept. Because one illustrated middle-rail detail conflicts with the source table, the approved BOM—not this image—controls the released geometry.

Round-System Components

Tube, tee, elbow, cross, foot base and kick plate

From Layout to Release

Six inputs for a coordinated industrial handrail system

Layout and terminology

Mark straight runs, corners, gates, stair flights, returns and openings. State whether each run functions as a handrail, guardrail or combined stair-rail system under the adopted code.

Load basis

Provide the governing point load, line load, infill load and deflection criteria. Post spacing, rail section, joints, bases and substrate must be checked together.

Base and substrate

Identify concrete, steel, FRP framing or side-mount conditions, with slab edge distance and available fixing depth. Catalog anchor sizes are not a universal anchorage design.

Exposure and finish

List chemicals, concentration, temperature, outdoor UV, washdown and electrical conditions. Resin, color, veil and metal hardware are then selected for the actual service.

Kick plate and openings

State toe-board requirements, platform edge detail, allowable openings and interfaces with grating, deck panels, ladders and stair treads.

Approved release set

Release the post schedule, tube system, fitting types, splice locations, base details, anchor schedule and BOM before production or field drilling.

Load-basis checkpoint. OSHA 1910.29 applies criteria to completed guardrail systems, while ISO 14122-3:2016 covers stairs, stepladders and guardrails within its machinery-access scope. Neither standard can be claimed from catalog tube sizes or post spacing alone.

Frequently Asked Questions

What is the difference between an FRP handrail and an FRP guardrail?

A handrail provides a graspable support along a stair or walking route. A guardrail protects an exposed edge and includes top rail, intermediate protection and sometimes a toe board. One assembly can perform both functions only when its geometry, graspability, loads and mounting satisfy the governing requirements for both.

What square-tube fiberglass handrail sizes are listed?

The source catalog lists 50 × 50 × 6.4 mm square top and middle rails, a 38 × 38 × 6.4 mm insert splice, 100 × 14 × 3 mm kick plate, 1,500 mm maximum post spacing and 1,220 mm maximum height. These are nominal catalog references, not a blanket load-compliance statement.

What round-tube FRP handrail components are listed?

The catalog lists 50 × 5 mm round-tube notation for posts, top rails and middle rails, a 101 × 14 × 3 mm kick plate, and molded elbow, tee, cross and foot-base fittings. Final tube interpretation, fitting detail, fastener material and base anchorage are confirmed on the approved BOM and drawing.

Do the fiberglass handrail systems comply with OSHA or ISO 14122-3?

They can be configured and evaluated against a stated project basis, but the catalog dimensions alone do not prove compliance. OSHA 1910.29, for example, evaluates the completed guardrail under specified forces; ISO 14122-3 has a defined machinery-access scope. Post spacing, rail section, joints, bases, anchors and substrate all affect the result.

Should I choose round or square FRP handrail?

Choose from the required handrail function, project geometry, fitting strategy, visual preference and approved load check. The round system uses molded tee, elbow and cross fittings; the square system uses internal splices and fabricated corner details. Do not swap components between the two catalog systems without a revised BOM.

What information is needed for an industrial FRP handrail quote?

Send total run, plan and elevations, stair slopes, height and post-spacing limits, governing load standard, base substrate, kick-plate requirement, exposure, color, gates and delivery destination. A marked drawing lets F1 return a coordinated post, rail, fitting, base and anchor schedule.
