Trusted by many, but far from perfect

Here are the most common issues faced with TMT bars, and how GFRP rebars can counter them

TMT Bar Issue

Prone to rust in moisture, coastal air, and chemicals

High density increases transport and labor costs

High resale scrap value leads to frequent theft

Vulnerable to acid, alkali, and salt exposure.

Not suitable for sensitive areas like MRI rooms or power facilities

Steel prices are volatile and globally affected

Maintenance, repair, and corrosion protection add up over time

Cutting and shaping leads to on-site material waste

Needs coatings or special treatment

Does not rust — ideal for marine, underground, and chemical environments.

Up to 75% lighter — easy to lift, transport, and install

No scrap value — virtually no resale market.

Withstands corrosive substances with no degradation

Safe for medical, electrical, and fire-sensitive structures

Not tied to global metal markets — more predictable budgeting

Durability reduces maintenance and long-term expenses

Easy to cut and shape with minimal waste

Performs in coastal, submerged, and chemically aggressive zones without coatings
