Frequently Asked Questions

What grades of steel are used for construction machinery parts?

Common grades include ZG270-500 (carbon steel), ZG20SiMn (low alloy), ZG30CrMnMo (quenched and tempered), and proprietary wear-resistant alloys. Material selection depends on the service conditions — impact, abrasion, temperature.

What's the typical lead time for construction castings?

Sample castings: 15-25 days. Production orders (1-20 tons): 25-45 days. Large batch orders: 45-60 days. Heat treatment and machining add 5-15 days. Rush orders available.

Can you handle large, heavy-section castings?

Yes. Some of our partner foundries have melting capacities of 20+ tons per heat, suitable for large machinery bases, press frames, and gear housings up to 50 tons per piece.
