What is specific about a 12×12 cm square beam?
The nominal cross-section is square - 12 cm on both axes, which simplifies geometric orientation but does not make the beam equally reliable in every direction. The arrangement of fibers, knots, cracks, and supports remains important. Shopify does not specify a strength class or actual deviations. For load-bearing use, check the marking of the specific piece and the design function.
What lengths are available for the 12×12 cm square beam?
The available catalog options are 3 m LT-4535, 4 m LT-4534, 5 m made to order LT-4533, and 6 m made to order LT-4532. When ordering, specify the SKU for each length, as the general name does not distinguish the cut. For the longer options, confirm straightness, delivery time, and transport, as well as whether unloading can be done without bending or dragging.
How is the volume of a 12×12 cm beam calculated by length?
The nominal area is 0.0144 m². The volume is 0.0432 m³ for 3 m, 0.0576 m³ for 4 m, 0.0720 m³ for 5 m, and 0.0864 m³ for 6 m. Multiply these values by the number of pieces for an approximate total volume. The invoiced calculation and actual cross-section should be verified because the product does not publish allowable deviations or moisture content.
How much larger is the 12×12 cross-section compared to 10×12 cm?
The nominal area of 12×12 is 144 cm², and of 10×12 is 120 cm², a difference of 20%. This is a comparison of geometric volume, not design load capacity. In bending, it matters which side is the height, as well as the strength class and the span. Replacing 10×12 with 12×12 can change connections, levels, and self-weight and must be coordinated.
What strength class does the 12×12 cm beam have?
Shopify does not specify a strength or visual grading class. There is also no information on wood species, moisture, drying, impregnation, or allowable defects. Therefore, class C24 or any other standard class should not be assumed by default. For load-bearing structures, request documentation and marking for the batch; without these, design characteristics cannot be traced to the specific product.
How should 12×12 cm beams be stored before installation?
Arrange them on flat, dry, and level supports, with enough bearing points to prevent warping. Protection should keep out rain but not trap moisture without ventilation. Specific rules depend on moisture and treatment, which are not published. Before installation, check straightness, cracks, knots, dimensions, and signs of biological damage.
