One Partner for MEP Materials and Project Support
Shanghai Hezongxin New Material Technology Co., Ltd. is a Shanghai-based electromechanical material distributor and technical service provider. Our core supply includes cables and wires, busbar trunking, distribution boxes, cable trays, PE pipes, PPR pipes and PVC pipes.
We serve MEP, fit-out and building general contractors, alongside overseas distributors of electromechanical materials. Our materials support building electrical, water supply and drainage, HVAC and fire-protection work.
Alongside material supply, our five technical services are building MEP drawing design, drawing refinement, construction cost estimation, quantity surveying, and construction process optimization.
Supply capability
Supply Capability for Cross-Category Project Procurement
HZX coordinates specification review, supplier matching and export execution for project orders that require more than a single product line.
For mixed RFQs, quotation accuracy depends on keeping specifications, supply routes, documentation and delivery requirements aligned from the beginning of the sourcing process.
Specification review
Drawings, standards, materials, quantity structure and application conditions are clarified before quotation is prepared.
Resource coordination
Different product divisions are matched with suitable domestic manufacturing and supply resources for both single-category and cross-category orders.
Export handoff
Quotation details, packing information, inspection points, shipping documents and after-sales communication remain connected through one contact window.
Seven Product Families for MEP Procurement
Cables and wires lead our range, followed by busbar trunking, distribution boxes, cable trays, PE pipes, PPR pipes and PVC pipes.
Cables & Wires
Power cables and building wires. Specify conductor configuration, voltage, cable construction and required lengths.
Busbar Trunking
Busbars, trunking and connection accessories. Share current ratings, route layouts and connection requirements.
Distribution Boxes & Cabinets
Distribution boxes, boards and cabinets. Include ratings, enclosure requirements and the relevant drawings.
Cable Trays
Cable support and routing products. Specify tray type, dimensions, finish, accessories and quantities.
PE Pipes
PE pipes and matching fittings for specified water supply and infrastructure applications. Include diameter, pressure class and jointing requirements.
PPR Pipes
PPR pipes and fittings for building plumbing. Share dimensions, design temperature, pressure requirements and quantities.
PVC Pipes
PVC pipes and fittings for the specified drainage or water application. Confirm the product type, dimensions and matching accessories.
Quality in materials. Integrity in cooperation. Practical expertise throughout the project.
HZX emphasizes specification accuracy, realistic sourcing routes, stable order follow-up and dependable execution across quotation, documentation and delivery.
Quality begins with specification fit
Application matching, document accuracy and supply consistency are confirmed before order execution moves forward.
Reliable cooperation depends on follow-up
Clear communication, realistic timelines and visible coordination are maintained throughout the sourcing and delivery process.
Project procurement requires execution discipline
Drawings, BOQs and product lists are aligned into clear quotation scope, coordinated sourcing steps and stable order follow-up.
One workflow keeps supply details connected
Quotation, packing requirements, inspection points and shipping documents remain aligned through one coordinated export workflow.
Five Engineering Support Services
Building MEP drawing design, drawing refinement, construction cost estimation, quantity surveying, and construction process optimization.
Tell us your project stage and the support you need. We will review the available documents and agree the scope and deliverables with your team.
Building MEP Drawing Design
Develop building mechanical, electrical and plumbing drawings around the agreed design brief, project requirements and coordination inputs.
Drawing Refinement
Refine existing MEP drawings with coordinated routes, installation details and interfaces informed by site conditions.
Construction Cost Estimation
Prepare construction cost estimates using the agreed drawing scope, quantities, specifications and pricing assumptions.
Quantity Surveying
Measure quantities from MEP drawings and verify BOQ items for tendering, procurement and cost control.
Construction Process Optimization
Review construction methods, installation sequences and trade interfaces to improve the planned workflow.

Supply-chain qualifications
Manufacturer documentation for informed procurement.
HZX is the material distributor and technical service provider. The qualifications below belong to the named manufacturers. Documents and approval scope are matched to the specific product offered for your project.
Shanghai Qifan Cable Co., Ltd.
- ISO 9001, ISO 14001 and ISO 45001 management-system documentation.
- CCC certificates covering specified cable products and models.
- CNAS-accredited manufacturer testing centre, registration L12009, with an ISO/IEC 17025 accreditation scope.
Ask for the relevant cable model, test scope and current supporting documents with your quotation.
Zhejiang Zhongcai Pipes Science and Technology Co., Ltd.
- ISO 9001, ISO 14001 and ISO 45001 management-system documentation.
- WRAS material approvals for specified blue HDPE pipe and fitting materials.
- Product catalogues and technical information for selecting pipe-and-fitting packages.
WRAS material approval concerns effects on water quality within its stated scope; it does not establish the complete mechanical performance of a pipe system.
Certification coverage depends on the manufacturer, product, model, application and destination. Include your required standards and approvals in the enquiry so the matching documents can be reviewed.
