What does the size 10×10 cm mean for a wooden beam?
The designation is a nominal square cross-section of 10 by 10 cm. It does not indicate length, wood species, moisture content, treatment, or strength class. Before structural use, measure the actual cross-section and request the sorting class and allowable deviations for the batch. Planing and drying can affect the actual dimensions, so connections should not be designed based solely on the nominal size.
In what lengths is the 10×10 cm beam available?
Shopify options are 3 m with SKU LT-4543, 4 m with SKU LT-4542, 5 m made to order with SKU LT-4541, and 6 m made to order with SKU LT-4540. The "made to order" label does not specify lead time or availability. Confirm the feasible length, number of straight elements, transport access, and whether the price is for a single whole piece before payment.
What is the nominal volume of a 10×10 cm beam?
Based on the nominal cross-section, the volume is 0.01 m² times the length: 3 m equals 0.030 m³, 4 m equals 0.040 m³, 5 m equals 0.050 m³, and 6 m equals 0.060 m³. This is a geometric calculation, not a guarantee of invoiced volume or actual dimensions. Upon delivery, check the measurements, moisture content, and allowable deviations of the specific batch.
Can a 10×10 cm beam be used as a rafter or purlin in a roof?
This cannot be decided by cross-section alone. The wood species and strength class, actual moisture, span, supports, snow load, wind, and position in the structure are all needed. Shopify does not publish this data. A designer must check the beam for bending, shear, compression, deflection, and connections. The 10×10 cm size is not a universal roofing element.
Is the 10×10 cm beam impregnated and dried?
This is not specified in the product. There is no data on wood species, moisture, kiln drying, planing, impregnation, or use class. Do not assume treatment based solely on the photo color. For roofing or exterior use, request a written specification for moisture and protection compatible with the installation site, metal connectors, and subsequent covering.
How do I calculate the number of 10×10 cm beams for a straight structural line?
The number depends on the design spacing and the length of the line, not just the cross-section. Once the designer sets the positions, count the support axes and add individual end, double, or reinforced elements from the drawing. Lengths of 3-6 m are arranged so that joints fall in allowed locations. Do not add a joint between supports without a structural detail.
