Product Characteristics
Counterweight steel sand is made from high-quality steel via a specialized process, with the following features:
High Density:
Density reaches over 7.4g/cm³, ensuring large counterweight in a small volume and saving equipment space.
Extreme Wear Resistance:
Treated with quenching + tempering, the surface hardness is HRC 50–62, minimizing wear during long-term use and extending equipment maintenance cycles.
Uniform Particles:
Through multi-stage screening, particle size deviation is controlled within ±0.2mm, ensuring stability and fluidity during counterweight operations.
Specification Parameters
| Item | Specification Range |
|---|---|
| Material | High-carbon steel (C: 0.8%–1.2%) |
| Particle Size | 0.2mm–5.0mm (customizable) |
| Density | ≥7.4g/cm³ |
| Hardness (HRC) | 40-60 |
| Wear Resistance | Weight loss rate ≤0.1% (500-cycle test) |
Applications
Counterweight steel sand is widely used in scenarios requiring high counterweight precision and stability:
Usage Scenarios
Elevator Counterweight:
Fill Counterweight steel sand into the counterweight frame according to calculated weight. Its high density precisely balances the car's weight, improving elevator operation stability and energy efficiency.
Crane Counterweight:
Filled into counterweight boxes, the steel sand's weight is adjusted with working conditions to ensure lifting operation safety.
Material & Manufacturing Process
Material: Selected high-quality scrap steel to ensure raw material purity.
Production Process: Medium-frequency furnace melting → atomizing granulation → quenching strengthening → tempering toughening → multi-stage screening → magnetic separation impurity removal → quality inspection and packaging. Each step strictly controls parameters like temperature and time to ensure product performance.
Quality Control
We have established a full-process quality inspection system:
Raw Material Inspection: Test carbon, sulfur, phosphorus, and other elements for each batch of scrap steel.
In-Process Inspection: Test particle size after granulation and hardness/density after heat treatment.
Finished Product Inspection: Randomly sample finished products for wear resistance, impurity content, etc., to ensure a 100% qualification rate.
User Guide
Calculate the required steel sand weight and particle specifications based on equipment counterweight needs (we provide technical support).
Choose appropriate packaging (ton bags/small barrels) to avoid moisture or contamination during transportation.
Ensure the container (e.g., counterweight box) is sealed well during filling to prevent steel sand leakage or impurity mixing.

Delivery & Samples
Delivery Time: 3–5 working days for regular specifications after order placement; 7–10 working days for customized specifications (adjusted according to order quantity).
Samples: 500g free samples are provided (customers cover shipping costs; free shipping for old customers). Sample quality is consistent with bulk goods.
After-sales Service
If there is a quality problem (non-human factor), return and exchange are supported, with round-trip freight borne by us.
Lifelong technical consultation is provided, such as counterweight scheme optimization and problem solving during use.
Certification & Qualification
The company is ISO9001 quality management system certified. Products meet third-party testing standards such as SGS and BV. We have import and export operation rights and complete production and quality qualifications.
