Cedar Beams vs. Machined Lumber: Which is Best for Your Patio Project?

When planning your outdoor patio, one of the most critical decisions you'll make is choosing the right material for your patio structure. With so many options available, it can be challenging to decide between natural cedar beams and machined lumber.

Before diving into the advantages of cedar beams, let's first understand what machined lumber is. Machined lumber, also known as engineered wood, is a type of wood that has been processed and manufactured into specific shapes and sizes for various construction purposes. Although some people prefer the look of machined lumber, it may not be the best choice for patios due to its strength properties and potential for lower durability. In this blog post, we'll explore the advantages of cedar beams over machined lumber for a free-standing patio structure with a roof, focusing on their tensile, compressive, shear, and torsional strength properties.

1. Tensile Strength: Why Cedar Has the Edge

Natural cedar beams boast excellent tensile strength, allowing them to resist breakage or deformation when subjected to tension forces. In contrast, machined lumber, though often engineered for specific purposes, may not have the same level of tensile strength as natural cedar. Cedar's ability to withstand tension makes it better suited for supporting a patio roof structure, especially during heavy snowfall or strong winds.

2. Compressive Strength: Cedar's Superior Load-Bearing Ability

Cedar is known for its impressive compressive strength, enabling it to bear significant loads without deformation. This property is essential in a patio structure, where the roof needs to be supported by strong, stable beams. Machined lumber can have varying compressive strength depending on the species and engineering process, but natural cedar consistently provides the necessary support for a free-standing patio.

3. Shear Strength: Cedar Resists Lateral Forces

Shear strength is crucial for patio beams, as it measures the ability of the material to resist forces that may cause it to slide or break along a plane. Cedar has a relatively high shear strength compared to other softwoods, making it better suited for resisting lateral forces that may affect the stability of a patio structure. Machined lumber may have lower shear strength, depending on the species and treatment process used, which could compromise the patio's stability.

4. Torsional Strength: Cedar's Resistance to Twisting Forces

Torsional strength is essential in a free-standing patio structure, as it determines the ability of the material to resist twisting forces. Natural cedar beams have good torsional strength due to their cellular structure and natural growth patterns, allowing them to maintain their shape under various forces. Machined lumber, however, might not have the same level of torsional strength, depending on the species and manufacturing process. This can lead to instability or deformation of the patio structure.

5. Aesthetic Appeal: The Natural Beauty of Cedar

Aside from strength properties, natural cedar beams offer an organic and rustic appearance that is difficult to replicate with machined lumber. Cedar's natural color, texture, and grain patterns create a unique and visually pleasing patio structure that is both functional and visually appealing.

6. Durability and Rot Resistance: Cedar's Long-lasting Advantage

Cedar is naturally resistant to decay, insect infestations, and rot. This makes it a long-lasting and low-maintenance choice for outdoor structures like patios. Machined lumber might require additional treatments to achieve the same level of durability and resistance, which can add to the overall cost and environmental impact.

The Bottom Line

Natural cedar beams provide a superior combination of tensile, compressive, shear, and torsional strength, making them an excellent choice for constructing a free-standing patio structure with a roof. The material's aesthetic appeal, durability, and natural rot resistance further enhance its suitability for this application compared to machined lumber. If you prefer the look of machined lumber, cedar can also be sanded down or wrapped in various materials like brick or stucco to achieve a more pleasing aesthetic. However, if you're looking for a long-lasting, visually appealing, and structurally sound option for your outdoor patio, natural cedar beams are the way to go.
