General Introduction Of Pallet Racking
Warehouse selective pallet racking is one of the best storage solutions to keep a wide variety of loaded heavy goods. The racking system is normally used for storing palletized goods, it is a storage solution that is designed to store materials on pallets that locate on the beam levels of the racking system so that a forklift truck can be used for easy and quick goods` handling in the warehouse.
Pallet racking is now an elemental request for most modern warehouses, a pallet racking system may increase storage density in a warehouse for goods stored there, therefore the pallet racking is a useful material handling storage aid system in the warehouse.
What Are The Features Of A Pallet Racking?
In warehouse storage, pallets on a pallet racking system can be easily located, accessed and moved, thus the rack system provides rapid handling of almost all types of goods palletized.
To meet special requirements, a pallet rack offers a wide range of optional choices and components, so the rack maximizes the use of warehouse space while retaining its optimum in product accessibility.
Strength and rigidity of a selective beam racking system offers great load capacity without damage to goods.
Bottom level of the racking system can also store pallets to save warehouse storage space and low the cost for buying the racking system.
A selective heavy duty pallet rack offers a load capacity of up to 4,000kgs per beam level, so the pallet racking system can meet warehouse storage demand of various manufacturing industries.
What Are The Components Of A Pallet Racking?
A typical pallet racking system for warehouse storage purposes mainly includes the components of horizontal loading beams, upright frames, and some other row spacers, wall ties, upright foot plates, safety locking pins, panel shelvind, wire mesh decking, upright column protector, guard rail, security fence.
1. Horizontal beam
There are three types of supporting beams that can be selected for a pallet racking.
• Step beam, the profile shape of this beam looks like low case character b, This step beam is used to hold and load support components such as pallet supports or wire deckings.
• Box beam, the profile of this beam is oblong shaped liked a box. it`s mounted on the uprights with hooks at both ends and locked or clipped to make the pallet racking firm and safe for storing goods.
• Structural beams, which is generally used with structural uprights but can be used with standard roll formed uprights. Structural beams are hot formed structural C shapes with connecting clips at either end to offer heavier loading capacities.
2. Upright frame
Upright frames is also called upright columns or uprights. The size and design of the upright frame may vary based on specific loading requirements and styles. The roll formed C shape upright is common for upright frames. In order that loading beams can be mounted into the upright columns, holes or slots are punched during manufacturing up and down the column at standard intervals. Compared with roll formed uprights structural uprights have an increased weight capacity over roll formed uprights by utilizing structural C shapes for columns.

Tips On How To Decide Pallet Racking
1. How to determine the width and depth of pallet racking?
A pallet and its entry side determines the width and depth of a pallet racking. Four-way entry pallets permit entry of forks from each side, two-way entry pallets only permit entry of forks from two opposite directions only. A 2-way entry pallets will restrict the direction you place the pallets on the racking.
For two pallets per beam level, a 2300(W) x 1000mm(D) rack is suitable for placing typical 1200 x 1000mm pallets with entry side at 1000mm direction:

Make sure the pallets should overhang beams at least 50mm to 100mm at each end. Clearance of 70mm to 100mm between adjacent pallets and pallet and upright.should be allowed. If the entry side of the pallets is at 1200mm direction, a rack of 2700(W) x 900mm(D) will be used:

2. How to decide the beam level of a rack?
The height of your palletized load is needed for deciding the beam level. And the height of your palletized load is the sum of the height of loaded goods and the pallet itself. A clearance of 100mm should be allowed between the top of the load and the underside of the beam to enable the lifting action of forklift.

3. How to determine the height of pallet racking?
First of all, the height of the top beam must be reached by your forklift truck. then the height of the rack with palletized goods should not exceed the height of the building. When deciding the height of the top beam, make sure there is enough space for storing goods beneath the ceiling.
4. How to determine the aisle width between racking?
The aisle width is the distance between racks. The turning radius of the forklift truck determines the width of the aisle。"working aisle" width which is the clearance between palletized goods after put on the racking. The aisle width is determined by the turning radius of the forklift truck. Forklift truck requires wider aisle than reach truck.
Although a minimum aisle width is suggested by forklift manufacturer, it is advisable for actual layout design to increase the width by approximately at least 200mm. For instance, a counter balance forklift of 3.0T capacity needs approximately 3,500mm to operate, however it`s necessary to take into consideration the pallet size, the bigger the pallet is, the bigger the aisle width is.
How To Install A Pallet Racking System?
To obtain the maximum benefit from the pallet racking system and for the safety consideration in the warehouse, prior to the assembly of the storage racking system, we suggest your reading below instructions firstly so that the warehouse rackings can be properly assembled and maintained.
Improper installation to the pallet racking will cause not only poor performance of the racking system but also lead to safety problems in your warehouse. If you have no experience in the installation, then it`ll be better to ask professional installers for help instead of having the racking system installed by yourself.
A carpenter level is needed as it`s important to keep pallet racking installed in a level, plumb, and square condition, and sometimes you have to shim the racks because of the uneven floor.
A working environment with safety protection measures is required for the installation in the warehouse.
Make sure necessary materials for assembling the whole rack systems are all ready in good conditions by checking them according to the project documents. Stage all materials in an organized manner so they can be quickly located.
Verify the correct location for the racks. Be sure the floor is level for a plumb installation of pallet racks. Warehouse storage racks are to be installed on a concrete floor. The floor slab must be thick enough to support the load from the columns of full loaded racks and to receive the installation of the anchors to the floor.
Check obstructions such as doorways, piping, electrical panels, lights, ducts, etc., make plans to avoid or remove them before installing pallet racks. Carefully verify column locations in the building.
Make sure adequate aisle widths are established and determine a starting line and snap chalk lines to layout the floor, Down-aisle chalk lines should be made at the front face of the pallet rack columns from the start line.
