How Do I Choose the Best Cheap Lumber?

Sheet material is a flat rectangular building material board of standard size. It is used in the construction industry as a component of walls, ceilings or floors. Also refers to metal plates forged, rolled or cast.

According to the material classification, the board can be divided into two categories: solid wood board and wood-based board; according to the molding classification, it can be divided into solid board, plywood,

Board purchase attention

Home decoration will definitely use boards, so how to choose boards, how to identify when buying boards, here are 5 points:

Plate purchase 1. Look for obvious flaws on the surface of the board

The surface of the decorative plate should be smooth, free of burrs and cutting blades, and free of glue penetration and surface pollution (such as local blackening and yellowing). Try to choose the surface of the plate without cracks, cracks, knots, leather, For resin sacs and gum channels, the natural warpage of the entire board should be as small as possible to avoid the phenomenon of sanding through the substrate due to improper sanding process operation.

Board purchase 2. Recognize the difference between thin wood veneer and natural wood veneer veneer

The texture of the former plate is basically straight texture, and the texture pattern is regular; the latter plate is a natural wood pattern, and the texture pattern has large natural variability and irregularity.

2. Purchase of plates Panel appearance inspection

The appearance of decorative boards should have good aesthetics, the material should be fine and uniform, the color and luster should be clear, and the wood texture should be beautiful.

4. Purchase of plates The structure of the sheet glue layer is stable, and there is no open glue phenomenon

Attention should be paid to the phenomenon of bulging and delamination between the veneer on the surface of the board and the substrate, and between the layers inside the substrate.

5. Purchase of plates To choose a board with low formaldehyde emissions

Do not choose decorative plates that have an irritating taste. The greater the board odor, the higher the amount of formaldehyde release, the more severe the pollution, and the greater the harm.

Board teaches you to identify

Blockboard: good moisture-proof effect, can not be painted directly

The core of the blockboard is a core bonded by natural wood strips, and a thin veneer is glued on both sides, which is one of the most important materials in decoration. Can be used for furniture and wooden doors and door covers, heating covers, curtain boxes, etc., its waterproof performance is good. When choosing, look at its internal wood, it should not be too crushed, and it is better to use a blockboard with a gap of about 3mm between the woods. Due to the unsightly appearance of the wood grain, it is rarely painted directly, usually with decorative plywood. The furniture and other wooden utensils made with it have to go through two processes of using adhesive boards and painting, and the cost is higher.

Integrated board: difficult to deform

This is a new kind of solid wood material, which is made of high-quality imported large-diameter logs, and is staggered and spliced like a finger. Due to different processes, this board has excellent environmental performance, which is 1/8 of the formaldehyde content allowed in blockboard. On the other hand, this kind of solid wood panels such as American spruce can be directly colored and painted, which saves a process compared to blockboard.

MDF: worse nail holding force than particleboard

Particleboard is the main material of cabinets after crushing natural wood into granules and pressing into boards. Medium density boards are formed by pressing powdered wood chips. The flatness is better, but the moisture resistance is poor. In contrast, MDF has a poorer nail grip than particleboard.

Facing triple plywood: save time and cheap

Multi-layer board, also known as triple plywood and plywood, is called differently depending on the number of layers. Its advantages and disadvantages mainly depend on raw materials. The main decoration used in home decoration is the triple plywood, that is, the very thin solid wood finish has been pasted on the triple plywood in the factory. Facing triple plywood is easy to use and cheap. ^[3]
