Sustainability

Tongjiang's environmental and energy performance is certified and audited, not self-reported. The company holds ISO 14001:2015 environmental management certification and ISO 50001:2018 energy management certification, and the energy certificate carries measured consumption data rather than a stated target.

The figures below come directly from those certificates.

Environmental and Energy Management at a Glance

Environmental Management System

Tongjiang's Environmental Management System is certified to ISO 14001:2015 (GB/T 24001-2016 equivalent, Certificate No. 18122E20706R1S), covering the production of steel wire rope within the company's qualification scope and the environmental management activities tied to that production. The certificate was first issued September 30, 2022, renewed September 29, 2025, and is valid through September 29, 2028.

Energy Management and Measured Performance

Tongjiang's Energy Management System is certified to ISO 50001:2018 (GB/T 23331-2020 and RB/T 119-2015 equivalent, Certificate No. 21125En10013R0S), issued October 10, 2025 and valid through October 9, 2028. The audit boundary covers the main production system (wire drawing, twisting, and rope assembly, using steel as the primary raw material), auxiliary production systems (power distribution and transformation, air compressors, environmental protection equipment, warehouses, testing equipment, and forklift transport), and the administrative office as an ancillary system.

Under that boundary, comprehensive energy consumption per ton of product was measured at 56.11 kgce for 2024 and 55.94 kgce for the January to August 2025 audit period, a 0.3 percent reduction confirmed under third-party audit rather than reported by the company itself.

Supply Chain Footprint

Tongjiang's Nantong facility sits in the Yangtze River Delta, one of China's most concentrated raw-material and manufacturing corridors. Wire rod arrives from nearby steel producers rather than from distant regions, which shortens inbound transport distances compared to a manufacturer sourcing materials from further afield.

Frequently Asked Questions

Is TJ Steel Rope's Environmental Management System certified?

Yes. Tongjiang holds ISO 14001:2015 certification (Certificate No. 18122E20706R1S), covering the environmental management activities tied to steel wire rope production. The certificate was renewed September 29, 2025 and is valid through September 29, 2028.

How is TJ Steel Rope's energy use measured and audited?

Energy use is certified under ISO 50001:2018 (Certificate No. 21125En10013R0S) and audited against a defined boundary covering the main production system (wire drawing, twisting, rope assembly), auxiliary systems (power distribution, air compressors, environmental protection equipment, warehouses, testing equipment, forklift transport), and the administrative office. The certificate is valid through October 9, 2028.

What was TJ Steel Rope's energy consumption per unit of product in 2024 and 2025?

Comprehensive energy consumption per ton of product was 56.11 kgce across all of 2024, and 55.94 kgce for the January to August 2025 audit period, a measured reduction of about 0.3 percent.

What production and auxiliary systems are included in TJ Steel Rope's energy audit boundary?

The main production system covers wire drawing, twisting, and rope assembly, using steel as the primary raw material. Auxiliary production systems include power distribution and transformation, air compressors, environmental protection equipment, warehouses, testing equipment, and forklift transport within the factory. The administrative office is included as an ancillary system.

Does TJ Steel Rope's location affect its environmental footprint?

The Nantong facility is located in the Yangtze River Delta, a concentrated raw-material and manufacturing region in China. That location shortens the distance wire rod travels from steel producers to the factory, reducing inbound transport compared to sourcing from more distant regions.
