Order of 10 m, the theoretical weight of 2.055 tons.

 

Due to the nature and significance of steel pipes P11, steel mill allows only positive tolerance negative tolerance, so that

 

Per square meter of its actual weight is greater than the theoretical weight to the extent permitted tolerances in accordance with standard steel pipe a positive 12.5%,

 

The correspondent of the weight can be 12.5%, which means that 59.554 tons of the theoretical weight of steel pipe is actually

 

Weight ranging from 59.554 to 66.998 tons

 

3 companies and have contractual requirements to ensure the delivery of several meters, and then became so may allow a 10% payment

 

The goods, which means that we order 470 m, the steel can be delivered to 517 meters, I should unconditionally accept only

 

Can the contract, or take steel may be plus or minus 5% of the supply, given the nature of deficits P11 steel pipes,

 

In order to avoid the use of your company is 10% of the time difference between the amount of the reasons why I chose to deliver
