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

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.

In 2025, stainless steel rebar typically costs between $3.50 and $8.00 per linear foot, depending on bar size, grade, order quantity and market conditions. For common #4 (1/2 inch) stainless steel rebar, most contractors see prices in the range of $4.50–$6.50 per foot for typical 304 or 316 grades, with premium duplex grades on the higher end.

If you are budgeting for a project, the best approach is to use the ranges below for early estimates and then request an updated quotation based on your exact size, grade and quantity.

Calculating the amount of steel rebar for a concrete project is essential if you want a strong slab or footing without overbuying material. This guide walks you through simple formulas, a quick weight chart and a full example so you can estimate both the length and the weight of rebar with confidence.

If you are still choosing materials, you can compare our wholesale steel rebar and durable fiberglass rebar options to match your budget and project needs.

Quick Answer: #4 Rebar Weight per Foot

Many people search for “#4 rebar weight per foot” because they need to estimate the total weight for delivery or lifting. In the US bar size system, standard carbon steel rebar has the following approximate weights per foot:

Cutting steel rebar the right way is essential for safe, long-lasting concrete structures. Whether you are a DIY homeowner cutting a few bars at home or a contractor working on a busy job site, knowing how to cut steel rebar safely and accurately will save you time, reduce waste, and help prevent dangerous failures.

In this step-by-step guide, you will learn how to cut steel rebar using both manual and power tools, which cutting method works best for different bar sizes, how to cut rebar at home without professional machines, and the safety precautions you should follow on every project.

Understanding Steel Rebar Basics

Rebar, short for reinforcing bar, is a steel rod used to strengthen concrete so it can resist tensile forces that plain concrete

Radiant floor heating is only as good as the insulation beneath it. Without a proper layer under your slab or subfloor, a big share of that heat drifts into the ground instead of into the room you’re trying to warm. That’s where radiant floor reflective foil insulation earns its keep: a thin, highly reflective layer that helps push more heat upward, boosting comfort and lowering waste.

Contractors, growers, and facility managers want three things from any insulation choice: predictable performance, easy installation, and a clear payback. This guide walks through how reflective foil works, where it fits (and where it doesn’t), and how to evaluate products before you buy.
