The board core is made of several strips of hardwood that run along the length of the board. The strips can often be made of different woods like, for example, bamboo, poplar, etc. However, it is quite difficult to say anything about the board by its core. This is why you needn’t pay much attention to it. Most importantly, it has to be made of wood. If it is, the name contains the word «WoodCore» or something like that.
This feature is perhaps the most important one when it comes to stiffness. The number of fiberglass layers directly affects the torsion and axial stiffness. Basically, the fibers in each layer are located along the strip. Therefore, combining different layers, the manufacturer can deploy them at an angle to each other. For example, the bottom layer is laid along the snowboard, the middle is at an angle of 45 degrees (clockwise), and the top one – at 45 degrees (counterclockwise). The wrap may be BiAxial, TriAxial, and QuadAxial.
BiAxial is a two-layer wrap. For example, 45\-45 or 0\90. It has a great deal of flexibility and low stiffness. This is the reason why it is used in inexpensive boards, suitable for beginners or girls, as well as in many freestyle and jib models. The manufacturers often note that it is the BiAx that makes the board weigh less. Well, if you have no questions concerning the first statement, let’s move to the second one...
TriAxial is a three-layer wrap, 45\0\45. It has fairly high stiffness and is the basis for snowboards suitable for freeride and softboot carving. Classic snowboards without special amplifiers, but with a three-layer wrap have a responsive and, at the same time, an extremely playful character. These are very lively boards. Most commonly, this wrap type significantly increases the cost of the board. It’s just another layer, though.
QuadAxial is a four-layer wrap, 45\0\90\45. It gives a board maximum stiffness, and the weight is shifted to the edge of the board. This one is mainly used for hardboot snowboards, so it rarely occurs in the models designed for regular boots.
At the factory, they also can apply a structure on a base since it helps the base not to stick to wet snow. If the sliding surface is too smooth, it will create a molecular attraction that will stop the board. The appearance of the structure may vary from thin longitudinal notches to quite distinguishable dimples.
When making a slider, manufacturers often use graphite as it is a very hard and durable material. Such snowboards are quite tenacious; they slide well and rarely get scratched. Unfortunately, they are also more expensive.
It is the top cover of the board, which protects the laminate from damage, and is also used as a layer for applying the design. Most often than not, they make prints under the lacquer. Such a practical and inexpensive way allows you to print any design you want.
Veneer sheet looks beautiful and authentic and appeals to surfing and its origins. Some manufacturers claim that it increases the stiffness of the board, but it is hardly significant, even if it is true. However, a poorly treated veneer may crack from constant contact with water. This was the case with some HoverCrafts of 13-14 and 14-15 years.
Some freestyle boards do not have a topsheet. The design is printed on the core laminate, which, of course, facilitates the total weight of the snowboard.
It is far better if the edges are made of stainless steel. If the edges are made of this material, on a board you will find the phrase «Stainless steel». If they are made of ordinary steel, you should not leave it in the bag after riding. The edges will be covered with rust in just a few days. The rust destroys them, so, in the future, it would be much more difficult to sharpen them. If it happened anyway, you should run a sand paper (150-200) over it. And before summer, the edges should be greased with silicone grease or mixes like WD-40.
The edges may be seamless or have 1-4 spots of an intersection. Seamless edges are more preferable because the joint point is always a weak one.
