- Choose wire mesh for wide, light-to-moderate slabs where crack control + fast installation matter (patios, sidewalks, many residential driveways).
- Choose rebar for heavier loads, thicker slabs, foundations, walls, and structural zones where reinforcement must be placed strategically.
- Use both when you want broad crack control plus added strength in high-load areas.
Concrete reinforcement is crucial for improving the long-term performance of slabs, foundations, and structural elements. Two of the most common options are rebar and welded wire mesh (often called wire mesh
Rebar (short for reinforcement bar) strengthens concrete structures by handling tensile forces that concrete alone cannot. If you’re asking what steel is rebar made of, you’re usually trying to confirm one of these: (1) the most common material used for rebar, (2) whether rebar is high carbon steel, or (3) how composition affects strength and corrosion performance. This guide gives a clear answer first, then a practical selection framework for contractors, engineers, and buyers.
Quick Answer: What Is Rebar Made Of?
- Most rebar is made from carbon steel (commonly referred to as “carbon steel rebar”).
- Rebar is not automatically “high carbon steel.” Carbon content varies by grade/stand
In the world of construction, the debate of fiberglass rebar vs. steel is becoming increasingly common. While steel has been the traditional king of reinforcement, fiberglass (GFRP) is challenging the status quo with superior longevity and strength-to-weight ratios.
Are you wondering "is fiberglass stronger than steel?" or comparing the long-term costs? This 2025 guide breaks down the key technical differences to help you choose the right material for your project.
Quick Comparison: Fiberglass (GFRP) vs. Steel Rebar
| Feature | Fiberglass Rebar (GFRP) | Steel Rebar |
|---|---|---|
| Tensile Strength | Higher |
Rebar steel (reinforcing bar) is the backbone of concrete construction. But when engineers calculate load capacities, they don't guess—they look for specific numbers. One of the most common questions we get is: "What is the tensile strength of rebar?"
If you are looking for a quick answer or a rebar tensile strength chart, you are in the right place. Below, we break down the critical differences between Grade 40, Grade 60, and high-strength options.
Quick Reference: Rebar Tensile Strength Chart
The "Grade" of rebar designates its minimum yield strength. Here is the standard ASTM data used in the US:

Searching where to buy acoustic panels is confusing because a lot of products are “decor panels” pretending to be acoustics. Real panels can reduce echo and make speech clearer—but only when the specs and placement match your room.
This guide breaks down the best places to buy in 2026, how to verify claims, and what’s worth paying for. If you purchase for projects or in bulk, wholesale sourcing can also simplify procurement; Wellco Wholesale positions itself as a factory-direct wholesaler across categories for trade buyers who want consolidated purchasing.
