How to Connect Wood to a Steel Frame Building

Quck answer

There are several ways to attach wood to a steel frame building:

1. Welding: Welding metal brackets or plates onto the steel frame and then attaching the wood to these brackets with screws or bolts.

2. Steel connectors: Using steel connectors specifically designed for connecting wood to metal. These connectors are usually fastened to the steel frame with screws or bolts, and then the wood is attached to the connectors.

3. Adhesive: Using a high-strength adhesive that is designed for bonding wood to metal. The adhesive is applied to both the wood and the steel frame, and then the two are pressed together and left to cure.

4. Clips and brackets: Using metal clips or brackets that are secured to the steel frame and then hold the wood in place. These clips or brackets can be screwed or bolted onto the steel frame.

It’s important to choose the method that is most appropriate for the specific application and to ensure that the wood is securely attached to the steel frame for safety and stability.


Constructing a building with wood or steel is a difficult task that requires a skilled team of workers to ensure precision and quality. Whether you are attaching a steel door frame to wooden walls or connecting wood to steel beam supports, the process of attaching wood to a steel framed building can be relatively simple as long as you have the necessary tools.

Step 1

Secure the piece of wood to the steel frame by creating pre-cut holes in the frame for the bolts to pass through. Use a drill to create guide holes that allow the bolts to go through the wood and into the steel frame. If you are attaching wood directly onto a steel frame, use bolts specifically designed for screwing into steel or metal. The bolts should have complete threading.

Step 2

Use a spade drill bit to countersink the guide holes by 1/4 inch. Insert a washer into the countersink and place the bolt into the hole.

Step 3

Put a nut on the exposed end of the bolt and tighten it in place using the appropriate wrench. To secure it firmly, add a lock nut (a slightly smaller nut) onto the bolt.
