The main product tyres are slashed tyres, light-calorized midday tyres, a series of 10 large lines of steel-mounted heavy meridian tyres, special tyres, etc., and nearly 2,000 specific varieties, with 4 million sets of tilted tyres per year, 15 million sets of midday tyres with light card, 4 million units with heavy weight and 100,000 units with special tyres. Certification of the ncc, dot, ece, gcc, inmetro, latu, quality management system iso9001 and ts16949, iso14001 environmental management system, gb/t28001 occupational health safety management system, and sa8000 social responsibility management system. Over the years, the consortium has focused on a plant approach based on high-start, high-quality and high-tech approaches, with technological adaptation and the creation of a technology-based industry that is fast-growing, with the expansion of the main tyre industry, building up a chain of up-to-down industries, with the main tyre industry at its core, supported by energy supplies and facilitated by the production of raw materials. The design and development of products in the whole steel series 295 and 245 were patented in china, the united states and australia, filling domestic gaps; semi-steel high-performance car tires have been serialized, high-end products such as snow tyres, environmentally friendly tyres, and suvs have been developed on their own and will become one of the large high-end car tire production bases in asia during the 1105 period; the company's rubber machine workshop is the third largest production base in the country; the cogeneration project, which uses carbon black tail gas and coal pyrotechnic gas, is a power plant for the integrated use of resources; the cement mill is integrated with two major projects, namely, the powdery mill and the dusty bricks, which dry up the plant's slag and indirectly protect the land resources of 200,000 cubic metres per year. The continuous improvement of the industrial chain of the circular economy and the consolidation of the four main business advantages of enterprise science and technology, management, brand names and markets have enabled shandong linglong to move away from a new modern industry with good economic performance, low environmental pollution, high technological content and resource advantage. Over the next few years, the consortium will continue to deepen its business reforms and expand its production operations in an effort to achieve the "1321" project, which is a team-building effort, with a total of 30 million tyres produced, and a sales target of over $20 billion to become a world-managed and technical tyre manufacturing enterprise.

It is a symbol of excellence in the product of an enterprise, of excellence and responsiveness of its employees. The logo is an abbreviated tectonic deformation in english, the dominant image of the chinese name and elliptical form of logo, the search for a stable base of tension in the comparison of elliptical sizes, the symbol of the specialization of enterprise technology and the popularization of services. The overall emergence is light and dynamic, reflecting firm robustness and flexibility in the competition of the industry. It is also like a booming wave, signalling the flourishing spirit of creation and the evaporation of businesses. At the same time, the logo as a whole uses a combination of elliptical and dynamic shapes, which are also dynamic, mutually reinforcing and accurately interprets entrepreneurship and culture。
