| 6 | Broken material grade B (six grade) | Car broken materials (no sacks, woven bags, rubber, plastic, alloy parts, etc.) | No obvious debris, no motor, no high copper content, Cu≤0.25% | Common broken material |
| 7 | Heavy scrap (seven grade) | Specifications ≤300?00?50 or less, weight ≤300kg | 300?00?50 or less, weight ≤300kg, Cu≤0.2% | In-plant scrap, such as bottom, running steel, slag steel, casting surplus, outsourcing heavy waste, etc. |
| Technical requirements: 1. Scrap steel includes ordinary carbon steel, high-quality carbon structural steel, carbon tool steel and carbon steel. It is not allowed to mix high alloy steel, non-ferrous metals, alloy rolls, cast iron, etc. Complete sets of waste machinery and structural components are not allowed. Closed tubes and containers, flammable and explosive materials and toxic substances are not allowed. 2. The sulfur and phosphorus content of scrap steel shall not exceed 0.05%. 3. The scrap steel is supplied according to the classification, and it is not allowed to mix. Otherwise, it should be piled up according to the lower level. | ||||

Undermount sinks are sinks installed under the surface of a worktop with a cut out made to the size of the bowl. It is not common for an undermount sink to come with a draining board but rather the idea is that water can be wiped towards the sink. The kitchen tap is installed separately unlike an inset sink and in the case of granite worktops, has a radial cut out to suit the shape of the sink. They are known as a modern kitchen design and are starting to appear more often.
