Metal Buildings Contractor Featured In News For Lean-To Installation

CDMG Metal Buildings, an industrial contractor based in Canonsburg, PA, is pleased to share that their work was recently featured in Metal Construction News. The article in question highlights a specific aspect of CDMG’s capabilities: constructing metal lean-to’s to quickly add additional usable space to an existing structure. The company specializes in the design and construction of metal buildings, which offer a host of benefits to their more conventional counterparts. As such, the team at CDMG Metal Buildings is proud to receive recognition for their work and the advantages it offers their clients.

A lean-to receives its name from the way it is built: rafters are ‘leaned’ against a wall to form an extra roof. These structures only have one slope and are dependent, at least partially, on the original building for support. While they may not offer as much protection as the building they are attached to; they offer reasonably robust protection from the elements to whatever is stored underneath.


As the article by Metal Construction News explains, it takes an investment of relatively fewer resources and effort to add another simple structure to a new or existing building. A lean-to, for instance, expands the usable space of the original construction, and the durability of such an addition is improved by the use of metal building materials. A lean-to can consist of an extra roof-like structure alone or have more walls added to form a fully enclosed structure.

Different types of lean-to’s exist, but the article quotes Thomas M. Corry, division manager, CDMG Building Systems, “The most economical solution for adding a lean-to structure is to utilize a metal building system that can provide clear span properties at approximately one half the weight of a conventionally designed structure,” says Thomas “[It] will provide the serviceability of a conventionally designed steel structure. Lean-to structures have a single-slope roof sloping away from a higher structure, but in certain instances lean-to structures can be constructed with gable roofs depending on the process-use requirements for which the lean-to is being constructed.”

Before installing a lean-to, the contractor must decide whether it is a reasonable proposition for the building and purpose in question. This can be determined by balancing the efficient use of steel (to achieve appropriate bay sizes) with a good economy of scale and cost. The existing building must also be evaluated to ensure it can support an additional structure — one point the article highlights is that matching the material of the lean-to with the first building may not be the most efficient path to take.

As some may expect, affixing a structure to another building, it was not originally designed with has the potential to leave room for unsound structural connections. To avoid this outcome, certain steps may be needed to ensure the structure meets engineering standards and is weatherproof. Failing to do so can nullify the advantages the project was intended to deliver.

Similarly, the durability of the lean-to can depend heavily on the original structure. Adding a lean-to to a building will increase the load it has to bear, so this needs to be taken into account prior to installation. The article states that an engineer can investigate a building to see if it can support a lean-to. In the event it cannot, they may be able to determine a means to reinforce the building in question so as to generate the additional support required prior to the installation of the lean-to.

In any case, thoroughly vetting the situation and taking all relevant factors into account ahead of time can drastically improve the odds of a lean-to’s successful installation. This can also cut down on errors that lead to delays and require further (unwanted) financial investment.
