Oak beam 30×30 cm

An oak beam with a head size of 30×30 cm or300x300 mm comes from an imposing oak tree. Such a tree requires about 150 to 175 years of growth time. Such beams are available in our range and are wind-dried for about 5 to 8 years. The wood has a beautiful straight grain, making it excellent for use as a construction beam in renovation projects or when building new homes.

Oak beam 30×30 cm or 300×300 mm

A common size for an oak beam is about 30×30 centimeters, for the purpose of large structures. This size is suitable for various applications, such as joists, timber structures or decorative beams. The beams are available in different lengths, ranging from oak uprights of 2.5 or 3 meters to long oak beams of 6 meters, 7 meters, 8 meters, 9 meters or even 10 meters. The beams can be brushed or planed as desired.

What head size do I need for my project?

In general, the rule of thumb is that you can count 5 cm for the height of the header gauge per length meter of span. Using this guideline, a 30×30 cm oak beam would be sufficiently strong for a 6 meter span. Always have a structural engineer calculate the exact dimensions required. An alternative to the standard 30×30 cm size is the 25×25 cm beam. Such a beam contains 30% less wood and is therefore 30% lower priced.

What is the weight of such a 30×30 cm oak beam?

The weight of an oak beam varies and after several years of drying process, is usually between 750 and 850 kg per cubic meter. The volumetric mass of oak is primarily affected by the moisture content. The longer a beam dries, the lower the moisture percentage in the wood. So a dry oak beam always weighs less than a freshly cut oak beam, which can weigh as much as more than 1,000 kg per cubic meter. Second, the density of a beam depends on the growth area; a beam with fine grain may be heavier than one cut from a tree that has grown faster. Here are some indications for weight: 30×30 cm / approximately 70 to 75 kg per linear meter 25×25 cm / approximately 48 to 55 kg per linear meter Want to know more useful wood information?

Oak outbuilding, carport or porch

Oak beams with a head size of 30×320 cm are also often referred to as 300×300 mm. Such dimensions are suitable for a variety of building applications, including oak porches, outbuildings, canopies or pergolas.

Why wind-dried oak beams?

Dry oak has some important advantages. Fresh oak initially contains 30 to 50% moisture, which can cause deformation in a project. Unlike fresh wood, wind-dried oak undergoes a process of at least five to 10 years of drying, resulting in more stable wood and also with a lower weight. It is less prone to deformation and cracking, and offers better protection against insects and mold.

What does an oak beam 30×30 cm cost?

The price of a 30×30 cm oak beam depends greatly on the number of years the wood has dried. The longer the wood is dried, the higher the quality and thus the price level. Secondly, the length matters, the longer the beam the scarcer and therefore more pricey. A wind-dried oak beam is usually pricier than freshly sawn oak. Despite a higher price point than fresh oak, the benefits may justify the investment for those who value quality or aesthetics. For a free customized quote, please contact us through this page.
