## How much does a 30 foot steel beam cost?

Steel Support Beam Prices By Length A 10 ft. steel I-beam costs $60 to $180, while a 30 ft. steel I-beam costs $180 to $540 on average. H-beams can cost as much as double but are stronger, and support spans up to 3 times longer.

## How much bearing does a RSJ need?

## What is the minimum end bearing for beams and girders?

1. A minimum of 1-1/2″ bearing is required for joists or other wood framing members that rest on wood, whether it’s on plates as shown in the upper right or whether it’s on beams or girders. A bearing surface of this size will avoid crushing the wood fibers.

## How big of a beam do I need to span 30 feet?

Re: I-beam size 30′ span I would design this with the beam in the 24′ dimension. Most span tables will allow much more than 15′ for 2″ x 12″ joists of almost any species commonly used for construction. A 24′ beam can probably be a GluLam using standard joist hangers for the joists.
