Reliable quality. Lower cost per ton.
Hefei Senno Metallurgical Machinery Co., Ltd. has been designing, manufacturing and supporting rolling mill guides since 2015, from Anhui, China. We supply steel mills directly, and the engineers who design the part are the people you deal with — from selection and drawing approval through to lead time and after-sales.

Why mills buy from us directly
Factory-direct pricing
You buy from the manufacturer, not a trading company. The quotation comes from the people who engineer and build the part, so a trader margin is not part of your price.
Engineers, in your language
Our export team works in English and sits beside the engineers, so drawings, tolerances and lead times are agreed in one conversation rather than relayed through three.
Built for repeat supply
Mills come back because the second order fits like the first: drawings stay on file, material and hardness are to the agreed specification, and wear parts remain interchangeable.
Hefei: a science city with a steel belt and a guide industry
Senno is in Hefei’s airport district, Anhui. The city combines national science infrastructure, a province-wide metallurgy and materials supply chain, and the machining depth a mill guide needs — one city, one chain, one responsible supplier.
Science and metrology
USTC and the CAS Hefei Institutes bring quantum, fusion, synchrotron and materials research — and the metrology habits we apply to a wear part.
Steel and materials
Anhui’s mills, casting and forging shops and heat-treatment lines sit within a few hours; 42CrMo, alloy and tool steel are selected for the duty.
Guide manufacturing
Since 2015: 8,000+ m², 100+ staff, ISO 9001, critical fits to ±0.02 mm and wear faces at HRC 58–62.
Humanities and the long view
Bao Zheng, Li Hongzhang, Luzhou and Chaohu — a city that thinks in decades, and a supplier that stands behind the drawing.
