What wood should be used for the gate sign?

In recent 10 years, the specifications, materials and prices of "wooden rafts" all over the country are basically unified locally.

Every city has carpenters who specialize in making wooden signs, and a phone call will be sent to every sign shop.

However, on the whole, the quality of these' re' brands is not very high, because their prices are relatively low.

You said 2 meters long and 0.35 meters wide, which is a common specification. But you didn't provide the thickness requirement.

Regarding the price, in Zhengzhou, a cheaper city, the price of a paulownia whiteboard (200×35×3 cm in length and width) is only 60 yuan; 4 cm thick, 70 yuan. ...

As for the wood used in the "raft", it can be said that it is very miscellaneous.

Many years ago, pine was used more. In recent years, because the number of wooden signboards, like other signboards, has increased by dozens of times, the problems reflected have attracted people's attention.

The main problems of "raft" are surface fading and overall brand cracking.

Pine is expensive and easy to dry. Don't think that high prices are necessarily good; Poplar, easily deformed; Tung wood has become the first choice for "Mupai" because of its low price and difficult deformation.

Some unit clerks make ridiculous amateur demands because they don't understand, or her leaders don't understand. In this way, their prices will be several times higher than ordinary signboards, but they have not achieved the expected results.

The fading problem of' raft' is painting, which has nothing to do with wooden materials.

The deformation of "raft" is not only related to the material, but also to the thickness of the brand. The thicker it is, the less likely it is to deform. It is also related to the dryness of wood when it is used. Therefore, a flat, bright, cheap and durable're', one is to choose suitable materials, and the other is to pay attention to the production process. Suggestions for your affairs are as follows:

1) uses paulownia.

2) The thickness is equal to or greater than 4cm. (400×60 cm is only used when the thickness exceeds 6 cm)

3) Use polyurethane paint with good weatherability.

4) The back of the card is required to be painted 2-3 times (generally, the back is not painted, but only painted with a layer of yellow advertising color to hide people's eyes and ears).

5) Require the use of dry wood. (Old paulownia is the best)

Of course, it will be better in weather resistance if the "wooden sign" is required to be soaked with antiseptic drugs in advance and become antiseptic wood. However, so far, we have not heard of this technology used in "raft".

For your reference, the above requirements are much cheaper than pine because of the low price of paulownia, but the price will be slightly higher in the same brand of paulownia, but this is the money to be spent on the cutting edge! Years later, you will still show your shrewdness.
