Cross-section
Equal side lengths, corner radius and dimensional tolerance; a solid bar has no internal cavity.

Fiberglass Square Rods
A solid square section gives fixtures and assemblies flat locating faces on every side. Send F1 Composite your section drawing and service conditions for a custom pultrusion review, including tooling, samples and secondary machining.

Define the product for your assembly
Insulating spacers, equipment supports, locating blocks and fabricated frames where a solid section and flat contact faces suit the assembly.
Material
Glass reinforcement with a resin selected for the actual temperature, chemical exposure and electrical requirements.
Finish and fabrication
Cut lengths, end finish, drilling and slots reviewed against the drawing; exposed fibers and cut edges need an agreed finish.
Send the required configuration for review. The quotation confirms availability, production or sourcing scope, tooling, minimum order, documents and delivery. Performance values must come from the offered grade and assembly.
Resolve these checks before ordering
CHECK 1
Solid bar or hollow tube?
Use a solid bar where machining stock or full bearing faces are needed. A hollow tube can save mass for a frame. Compare stiffness, local bearing and the connection rather than choosing by outside dimensions alone.
CHECK 2
Fiber direction and holes
Most continuous fibers run along the rod. Transverse holes and short end distances can govern a connection even when the axial material strength is adequate.
CHECK 3
Qualification
Agree on dimensional inspection, straightness, surface acceptance and the relevant mechanical or electrical tests on the offered section before releasing a production order.
Fiberglass Square Rods: purchasing questions
Are square rods the same as square tubes?
No. Square rods are solid throughout; square tubes contain a cavity. Their weight, stiffness and connection details differ.
Can I order a standard size immediately?
Send the requested section first. F1 will confirm tooling availability, material, minimum order and delivery in the quotation; this page is a custom inquiry range.
