How to choose the right wood pallets / wooden boxes? 

 Tray Size 
 According to the standard pallet size and storage of materials to determine the size of the tray. Suggested possible use of standard pallets. Companies should try to use these types of specifications tray for easy exchange and reuse of pallets. (Currently used standard pallet size four, respectively, 1200mm × 1000mm, 1200mm × 800mm, 1140mm × 1140mm and 1219mm × 1016mm). 
 The choice of pallet size top priority transport and transport equipment size specifications. Pallet size should be appropriate just to meet the transport size, this can increase the space of adequate and reasonable means of transport used, save transportation costs, in particular, to consider the containers and trucks of the box size. Second, the size of the warehouse should also be considered, the size of the cargo box; pallet load of goods according to the packaging specifications to select the appropriate size of the tray, maximize the use of tray surface. Meanwhile, the flow of pallets loaded with goods, will directly affect the choice of pallet size. Typically, the cargo destined for Europe to choose 1200mm × 1000mm pallet, the cargo destined for Japan to choose 1100mm × 1100mm tray. 

 Tray material 
 Depending on your environment, choose a different tray materials. 
 1) Temperature: The temperature directly affects the different material of choice to the tray. This is because different materials play tray with the performance of normal temperature range. For example, the use of plastic pallets in temperature between +40 ~ -25 ℃. 
 2) humidity: Some materials, pallets due to strong moisture absorption, such as wooden pallets can not be used in humid environment, otherwise it will directly affect the life. 
 3) Environmental cleanliness: a high degree of environmental pollution must be selected on the pollution-resistant, easy to clean tray. Such as plastic pallets, pallets and other wood composites. 
 4) whether exports: imports of goods for many countries the use of packaging materials required for fumigation insecticide-treated, for export pallet shall be free to select a composite pallet fumigation. 
 5) load requirements: steel pallet is generally only to solve the problem of carrying heavy cargo was used, the overall structure of plastic tray is a tray, suitable for working, not damaged, but not as good as wooden pallets carrying capacity. Rigid wooden pallets, most of the logistics in the workplace can be used. 

 Tray structure 
 There are different ways the structure of the tray, according to the characteristics forklift forks, load requirements and other conditions required to select the application. Tray to tray directly affect the structure of the efficient use of a suitable structure can give full play to the characteristics of forklift operating efficiency. Tray to use as a ground floor plate, that is no longer moving pallets loaded with goods, but to play the role of water moisture, choose simple, low cost pallet, such as simple wooden tray, the tray should be noted however, the static load. 
 For transport, handling, loading and unloading of pallets, to select high strength, dynamic load large tray. This type of tray due to repeated use, and to use with the forklift and therefore require a higher intensity of the tray, the tray so that the structure is required "field" lines or "Chuan" line. After loading cargo pallet according to whether stacking, decided to choose one side or both sides of the tray. Since only a single tray bearing surface, not suitable for stacking, or likely to cause damage to the underlying goods, so stacking is required after a cargo, and must try to choose double-sided tray. If the tray is used in three-dimensional database on the shelves, but also consider the structure of the tray on the shelf for code. Since usually only in two directions to take goods from the shelves inserted, so for the tray on the shelves into the sides should try to use the pallet fork, fork truck so easy to take the goods, improve work efficiency. This tray is generally the structure of the lines selected fields. 

 Cost 
 Wooden pallet, low cost, but China is currently no standard tray, wooden tray with a structure due to the use of material or process differences, the quality varied widely, the market price changes, at 50 yuan to 300 yuan. Wooden pallets easily damaged if mismanagement, but can be repaired. As oil prices rise, the cost of plastic pallets to be much higher than wood pallets. Life than wooden pallets plastic pallets long, but can not repair damaged. 

 Wooden tray features: 
 Wooden pallets of wooden materials, drying setting treatment to reduce the moisture, eliminate stress, and then cutting, planing, decapitated, pumping side, sanding and other finishing plate processing and the formation of profiles, the use of anti-off function with Nailing (case by case basis using nut structure) will be bound into a semi-profile plate tray, and finally finishing, non-slip handle and sealing wax. 
 Wood material: wood pallet materials currently mainly pine, iron shirt, fir, and other miscellaneous hardwood, representatives of different materials, different pallet performance. European pallet standard clearly states you can not use poplar. 
 Moisture content: moisture content of wood pallet of the original impact of pallet of shrinkage, or cracking. Application of its high moisture content of the standard tray indicators, there are strict controls. European standards for wood pallets wood moisture content can not exceed the quality of the dry state, 22%, 22% to 26% range is defined as a small defect, more than 26% that failed. 
 Wooden pallets advantages: bending strength, rigidity, load capacity, low cost, easy maintenance, low temperature and high temperature performance, wide application. 
 Wooden tray Disadvantages: poor impact resistance, the frequent turnover in the use of easy to damage, life is short; easy damp and difficult to clean. 
 Types of pallets 
 We usually say the tray generally refers to flat tray. Flat pallet is almost synonymous with the tray, because the most widely used flat tray, use the largest number, most versatile. Flat tray can also be classified in the following manner: 
 1, according to the classification table. A single form, single use type, double-sided use of other four-and wing; 
 2, according to the classification of forklift fork into the way we usually say tray generally refers to flat tray. Flat pallet is almost synonymous with the tray, because the most widely used flat tray, use the largest number, most versatile. Flat tray can also be classified in the following manner: 
 1, according to the classification table. A single form, single use type, double-sided use of other four-and wing; 
 2, according to the forklift fork into the way of classification. Into a one-way fork-type, two-way fork entry type, entry type, three four-way fork. 
 The type of tray. There are one-way fork entry type 
 , Two-way fork entry type, entry type, three four-way fork. 
 3, according to the material classification. Wooden flat trays, steel flat trays, plastic flat trays, flat trays, and composite materials in five different paper tray. 
 4, according to the material classification. Wooden flat trays, steel flat trays, plastic flat trays, flat trays, and composite materials in five different paper tray. 
 In addition to flat tray, the following types of trays: 
 1 column tray. Column tray is divided into fixed and removable two, its basic structure is the four corners of the tray with steel columns, beams columns available top link, the formation of framework type. The main role of the tray column, one column to support the weight of material used, to the high-stacked; second is to prevent the goods placed on pallets in the shipping and handling phenomenon occurred during the collapse pile. 
 2, box-type pallets. Box tray is surrounded by a side of the tray, and some box on the roof, the roof and some do not. Box plate with fixed, folding, removable-type three. Four weeks with the tailgate plate, grid type and network type, therefore, surrounded by fence to fence-style box, also known as cage pallet warehouse pallet or cage. Box Pallet protective ability to prevent stack collapse and damage to cargo; loadable shaped stacking of goods can not be stable, and wide application. 
 3, wheel tray. Wheeled pallets and pallets and box pallets column compared to more than the lower part of the small wheels. Thus, the wheel tray can display a short distance move, carry or roll on roll off their own style of handling such advantages, the versatility and applicability. 
 4, Special Purpose tray. As the tray, high efficiency, security and stability, especially in some situations that require fast operation, highlighting the importance of using the tray, so countries have developed a variety of trays. 

 Wood pallets (wood pallet): natural wood as raw material to manufacture pallets. Is now the most widely used, because of its cheap, strong. 
 The main parameters: length / width / height / length and breadth error / diagonal error / rated load / maximum stacking layers / deflection / non-slip surface coefficient. 
 Advantages: high accuracy, distortion, high-strength screw reinforcement, not from the nail, solid and good.
