Product Introduction

Steel Cord Conveyor Belt for Heavy-Duty Bulk Transport

This product is positioned for project buyers handling heavy bulk materials on long-distance or high-tension conveyors. GRAND RUBBER confirms the ST grade, belt width, cord arrangement, covers, reinforcement, splice plan and inspection scope from the conveyor data instead of treating each parameter as an isolated choice.

Buyer-Focused Advantages

• ST grade is selected from design tension, conveyor layout and project duty.
• Cord diameter, pitch and quantity are confirmed together with belt width and ST grade.
• Top and bottom covers are matched to abrasion, impact, material and environmental duty.
• Splice, roll division, inspection and documents are planned before production.

FAQ

Who is GRAND RUBBER?

GRAND RUBBER is the brand of QINGDAO GRAND RUBBERS CO., LTD., an engineering-focused supplier of conveyor belts and industrial rubber products.

How is the ST grade selected?

We review conveyor length, lift, capacity, speed, power, take-up, design tension and safety basis before confirming the steel cord grade.

How are cord diameter, pitch and quantity confirmed?

They are linked to the selected ST grade, belt width and ordered construction; they are not chosen as independent default values.

Can rip protection or a breaker be added?

Transverse reinforcement, breaker or rip-protection directions can be evaluated when the impact and project requirements support them.

Which standards and documents can be supplied?

The applicable DIN 22131 or EN ISO 15236 edition, test basis and document scope are confirmed for the ordered project where required.

How is steel cord belt quality controlled?

Applicable controls cover steel cord, compound, belt building, vulcanization, dimensions, cord geometry, adhesion and agreed inspection items.

Can X-ray or ultrasonic inspection be arranged?

It can be discussed for applicable steel cord projects, subject to the agreed method, scope, timing, acceptance criteria and cost.

How is roll division and packing planned?

Roll length, joint plan, roll diameter, weight, transport limit, wrapping and shipping marks are confirmed for the project.

How are quality complaints handled?

Within one hour we acknowledge and register the case, assign a responsible contact and request evidence. Conclusions and remedies follow the investigation.

How are lead time and customization confirmed?

They are reviewed after the ST grade, width, covers, cord structure, reinforcement, roll division, inspection and packing are finalized.
