News Summary: PB-II bridge deck waterproof coating does not have a unified price per ton that is detached from the product type, technical requirements, and delivery conditions. When requesting quotations for a project, in addition to asking how much it costs per ton, it is also necessary to confirm the applicable requirements, specific performance, purchase quantity, packaging specifications, delivery location, and whether the testing and submission documents correspond. Otherwise, different quotations may not be directly comparable.
Many engineering procurement teams, when inquiring about PB-II bridge deck waterproof coating for the first time, usually ask directly: "How much is it per ton?"
This is a normal procurement question. However, if the manufacturer only quotes a price per ton and the two parties have not confirmed the specific technical requirements, it is actually very difficult to judge whether this price is high or low.
PB-II is an engineering-type bridge deck waterproof material. Even when it is similarly labeled "PB-II," the product requirements, testing documents, purchase quantity, and delivery conditions behind the quotation may differ. Therefore, a more practical approach for engineering procurement is to first clarify the conditions corresponding to the price.
Why can quotations differ even when they are all called PB-II?
First, it is necessary to confirm whether the quotation corresponds to the same type of technical requirements.
Taking an existing batch of Wanqiao's PB-II polymer-modified asphalt bridge deck waterproof coating documentation as an example, this batch was tested according to the relevant requirements of JC/T 975-2005 Type II. Its measured solid content was 53%, tensile strength was 1.1 MPa, elongation at break was 920%, and bond strength with cement concrete was 0.7 MPa. Under the conditions of 0.3 MPa and 30 min, all three specimens were impermeable.
These data are not intended to show that "the larger the number, the higher the price must be," but rather to illustrate a procurement issue: before comparing prices per ton, it is necessary to first confirm whether the products being compared are under the same technical conditions.
If one quotation corresponds to a different material type, low-temperature requirement, bonding requirement, or testing documentation from another quotation, merely comparing "how much cheaper per ton" can easily become meaningless.
50 kg per drum - how do you convert between price per ton and price per drum?
The packaging specification indicated in Wanqiao's documentation for this batch of PB-II is 50 kg/drum.
Based on this packaging, the calculation is: 1 ton = 1000 kg = 20 drums.
Therefore, if the project receives a price per drum, you can use: 50 kg drum price × 20 = corresponding amount per ton of material.
If you receive a price per kilogram, then: unit price per kilogram × 1000 = corresponding price per ton.
However, this is only a mathematical conversion of the material amount. When actually comparing quotations, it is also necessary to continue confirming whether tax is included, whether transportation is included, and whether the quotation conditions corresponding to different purchase quantities are the same.
When requesting project quotations, it is recommended to provide all this information to the manufacturer at once.
For example, if a bridge deck project plans to purchase PB-II, rather than only sending "How much is PB-II per ton?", a more effective inquiry message could be:
"The bridge deck project uses PB-II. The project requires Type II. Estimated purchase quantity is XX tons, delivered to XX region. Product test reports, TDS, and certificate of conformity are required. Please quote under the same conditions."
The more complete the information the manufacturer receives, the more comparable the returned price will be.
Especially for engineering projects, it is also recommended to confirm the following in advance:
Whether the product type is consistent with the design or project requirements;
What testing basis is used in the test report;
Whether the product name in the report corresponds to the product actually supplied;
What the packaging specification is;
What the estimated purchase quantity is;
Whether the quotation includes taxes and transportation;
Whether project submission and approval require technical documents such as TDS, test reports, and certificate of conformity.
A quotation obtained in this way is more suitable for engineering procurement decisions than simply asking "What is the lowest price per ton?"
When the quotation is particularly low, do not rush to judge whether it is cost-effective.
A low price does not automatically mean there is a problem with the product. Likewise, a high price does not necessarily mean it is more suitable for the project.
When encountering quotations with obvious differences, what is more worthwhile is to break down the quotations and compare them.
For example:
One quotation corresponds to the relevant requirements of PB-II Type II;
Another quotation only says "bridge deck waterproof coating";
One can provide testing documentation corresponding to the actual product;
The other only has a product name, with no clear correspondence between the documents.
In this case, the two "prices per ton" are actually not completely identical procurement objects.
What engineering procurement should compare is: the price under the same requirements and the same delivery conditions.
Not simply the smallest number in the table.
Why should testing data also be considered when purchasing PB-II?
Price addresses the issue of procurement cost, while testing data addresses the issue of "what exactly is the material being purchased?"
For example, in the aforementioned batch of Wanqiao PB-II:
Solid content was 53%;
Tensile strength was 1.1 MPa;
Elongation at break was 920%;
Bond strength with cement concrete was 0.7 MPa.
These specific data can be checked against the corresponding standard requirements and project documents.
Compared with promotional descriptions such as "good quality" and "stable performance," clear test items, test conditions, and batch results are more convenient for procurement, technical, and submission personnel to verify.
Guangzhou Wanqiao Building Materials Technology Co., Ltd. currently provides bridge deck waterproof materials such as PB-II, FYT-1, and AMP-100, and can provide corresponding TDS, test reports, product certificates of conformity, and other technical documents for specific products. For actual project selection and procurement, the design documents, project requirements, and corresponding batch technical documents shall prevail.
Therefore, if the question is asked again: "How much is PB-II bridge deck waterproof coating per ton?"
The more accurate answer is not to first give a fixed number detached from conditions, but to first confirm: what type, what technical requirements, how much to buy, where to deliver, and what documents are needed.
Only after unifying these conditions does this "price per ton" truly have comparative significance.
