The price of a 6 inch steel I beam varies with grade, length, and market conditions. Typical costs are driven by material weight, finish, and delivery logistics. This guide provides cost ranges in USD and practical factors to estimate a project budget.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 6″ Steel I-Beam (per linear foot) | $6 | $9 | $12 | Standard carbon steel, average grade |
| Beam (e.g., 20 ft length) | $120 | $180 | $240 | Based on per-foot price × length |
| Delivery (regional) | $50 | $100 | $150 | Depends on distance and curbweight |
| Fabrication/ Cutting | $50 | $150 | $350 | Edge prep, notching, or welding adds cost |
| Assembly/Installation Labor | $100 | $250 | $500 | Includes rigging and site prep |
| Permits & Fees | $0 | $50 | $500 | Jurisdiction-dependent |
Overview Of Costs
Cost for a 6 inch steel I beam centers on length, grade, and delivery. Typical total project ranges for mid-range projects fall between $500 and $2,500 for modest spans, assuming standard carbon steel and a single beam. Assumptions: region, specs, labor hours.
Low- to high-end ranges cover both material-only and turnkey scenarios. If a project requires multiple beams, heavier grade, or specialty finishes, costs can exceed the high end quickly. Per-foot pricing provides a quick estimate, while total prices reflect length and service needs.
Cost Breakdown
Materials dominate the cost, with per-foot prices guiding the base. Heavier grades or longer spans increase material weight and price.

| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $6/ft | $9/ft | $12/ft | Carbon steel, standard sections |
| Labor | $100 | $250 | $500 | Installation and rigging |
| Equipment | $20 | $60 | $120 | Crane, lift, clamps |
| Delivery | $50 | $100 | $150 | Distance-based |
| Permits | $0 | $50 | $500 | Building authority fees |
| Other | $0 | $30 | $100 | Waste disposal, incidental costs |
What Drives Price
Material weight and beam depth influence base costs, with heavier beams increasing per-foot prices.
Length and quantity dramatically affect totals; longer spans require more material and potentially more installation crew time.
Regional logistics impact delivery fees and availability of stock.
Ways To Save
Shop multiple suppliers for quotes to compare per-foot pricing and bulk discounts.
Consider standard sizes to avoid custom fabrication charges; plan for off-the-shelf sections where possible.
Coordinate delivery with project milestones to minimize hauls and idle crane time.
Regional Price Differences
Urban areas typically incur higher delivery and labor costs due to higher wage scales and restricted access.
Suburban markets often balance availability with moderate logistics costs.
Rural regions may offer lower labor rates but higher delivery fees if stock is dispersed.
Labor, Hours & Rates
Installation time varies by beam length, site access, and existing structure. A typical crew schedule might be 4–8 hours for a 20 ft beam, excluding permits.
Labor rates commonly range from $60-$150 per hour depending on region and required skill.
Additional & Hidden Costs
Hidden costs can include field fitting, coating or painting, and corrosion protection.
Waste disposal and site cleanup may add modest fees at the end of the project.
Real-World Pricing Examples
Basic scenario: One 20 ft 6″ steel I beam, standard grade, no coating; delivery; simple on-site placement. Total around $420-$900.
Mid-Range scenario: Two 20 ft beams, standard grade, light fabrication, crane-assisted install, delivery; permits. Total around $1,000-$1,900.
Premium scenario: Three 20 ft beams, premium grade or specialized finish, extensive field cutting, full rigging, expedited delivery, and permits. Total around $2,200-$4,000.
Assumptions: region, specs, labor hours.
