For different project locations, scale and requirements, Wison Engineering contracts qualified suppliers in the global market through flexible procurement modes such as strategic cooperation, framework agreement and centralized procurement, etc., to provide the best products and value-added services for the clients. 

Strategic Partnership  Wison Engineering engages the industry's leading manufacturers through long-term cooperation agreements, to realize the sharing of resources and benefits as well as access to technical support and capacity priorities. 

Framework Agreement  For general equipment materials, as well as a small number but high frequency purchase materials, Wison Engineering normally locks the price of equipment materials with high price sensitivity through the signing of framework agreements with suppliers.  This enables Wison to effectively control resources and deployment of surplus materials to achieve long-term win-win cooperation with suppliers. 

Centralized Procurement  The core equipment materials in the energy and petrochemical projects involves an extensive  purchase amount and highly professional technical requirements. Wison Engineering has formed a scale advantage through centralized procurement and utilizes the collective wisdom of the expert procurement team to effectively reduce procurement costs and achieve resource integration advantage. 

Site Procurement  For temporary and small-sized equipment materials required for project construction, as well as materials that need urgent procurement on site, Wison Engineering provides flexible and efficient on-site procurement services to meet the project requirements.
