Metal Crowd Control Barriers Price

Tube thickness greatly affects the price of metal crowd control barriers. Thicker tubes use more steel, which increases material costs. Therefore, barriers with thicker tubes are more expensive.

Freight cost also influences the price. Shipping heavy metal barriers can be costly, especially over long distances. If freight costs rise, the overall price of the barriers goes up.

Steel price is another key factor. When the market price of steel increases, production costs for the barriers rise. This leads to higher prices for the finished product.

The currency exchange rate between USD and Australian dollars impacts the price as well. If the USD strengthens against the Australian dollar, importing barriers becomes more expensive for Australian buyers. Conversely, if the Australian dollar strengthens, the barriers become cheaper.

In summary, tube thickness, freight cost, steel price, and currency exchange rates all play significant roles in determining the price of metal crowd control barriers.

How to Pack Crowd Control Barriers

The standard method for packing crowd control barriers involves placing the panels onto metal pallets. To maintain the balance of the entire pallet, it’s important not to have all the round top sides facing the same direction. The correct packing procedure is to alternate the orientation: one piece with the round top facing one way, then the next piece facing the opposite direction.

The packing methods differ between galvanized crowd control barriers and polyester powder-coated crowd control barriers. The notable difference is that for powder-coated barriers, a layer of plastic film is placed between each barrier to protect the finish. The sequence is: one layer of plastic film, then one barrier, followed by another layer of plastic film.

Typically, OD25mm crowd control barriers are packed with approximately 100 pieces per pallet. 32mm crowd control barriers usually have 75 pieces per pallet, and 38mm crowd control barriers are packed with about 65 pieces per pallet.

Generally, the steel plate feet of the crowd control barriers are placed into the upright spacing between the barriers for efficient use of space. In orders with higher requirements, the feet are often placed in cardboard boxes for additional protection.
