Steel roofing, an environmentally friendly and highly recyclable material, has proven to be a powerful material for improving safety in China.
The material is now used in a wide variety of products, including solar panels and the roof of a number of luxury condominiums in the country’s northern province of Qingdao.
But some experts say the material’s popularity is in part due to a lack of regulation in China, which has been under a series of new environmental regulations since the beginning of the year.
In July, the Ministry of Environmental Protection banned the production and sale of roofing products that emit toxic substances, a move that has forced some companies to stop producing roofing.
The restrictions also included the production of steel products, which were considered too toxic to be manufactured in China and the country has imposed stricter emissions standards on other materials such as plastic.
A survey conducted by the Environmental Protection Institute, a Beijing-based think tank, showed that steel roofers in China had been using the roofing material since 2009, and the average number of roofers per capita in the region is around 1,200.
But the institute noted that a large percentage of steel roofer jobs are in rural areas.
The survey also found that, in 2011, around 10% of roof panels in China were made with steel, compared to about 6% in the United States.
While the study did not give a breakdown of the percentage of jobs in China’s steel industry, it did say that in China the steel industry accounts for a significant proportion of the economy.
“The reason why steel roof has become so popular is because the quality and the durability of the material are so good,” said Yang Liu, a research associate at the institute and the lead author of the study.
“The steel roof is made of carbon, so it’s recyclible.”
A recent report by the institute found that steel has the highest carbon footprint of any material in the world, and that the steel that was used in China was far more carbon-intensive than the materials used in other industrial sectors, including cement and steel.
“We’ve found that there are some industries where steel roofs are not used at all, and others where they are used to make certain kinds of materials,” Liu said.
The institute has found that the carbon footprint is so low that it can reduce the emissions of certain industries such as construction and the transportation of materials, Liu said, noting that the use of steel in roofing has also helped the country meet the Paris climate agreement goals of cutting greenhouse gas emissions by 26 to 28% by 2050.
However, some experts argue that while steel roof materials are environmentally friendly, the environmental impact of these materials can be more difficult to quantify.
The Environmental Protection Commission in the Chinese city of Chengdu recently issued a report on the environmental impacts of the roof material and said that the number of complaints about steel roof products has increased in the last few years, with more than 2,600 complaints from customers and workers since 2013.
In total, the company has received more than 4,000 complaints about its products, the report said.
One of the main complaints against steel roof paneling is that it is too heavy for construction work, with some studies estimating that a single panel can weigh as much as 1,500 kilograms (3,300 pounds).
But the EPC report said that “it is the quality of the product and the fact that it has been manufactured in a way that minimizes the use, recycling, and disposal of materials that significantly improves the environment and human health.”
While the use and recycling of steel panels is generally viewed as an industry-wide issue, the institute said that there have been cases where some steel roof producers have chosen to stop using the material altogether.
Liu said that while there have not been any cases of steel roofs being exported to other countries, he has been aware of a handful of cases of manufacturers in China who have been allowed to export their products, such as in the case of the steel roof material in Qingdong.
He said that these companies have not stopped producing the product in order to sell it domestically, and he has no evidence that any of them have been fined or forced to cease manufacturing.
But even if these cases do not happen, Liu says that the EPA report shows that the roof is still a good material for roofing in China because it is very inexpensive and can be made from recycled materials.
“Steel roofing is a very efficient material and the quality is very good,” Liu explained.
“I think the government will continue to use it and I think it will be exported to many other countries.”
