A Co Tyrone manufacturing firm is increasing production of its machines by around 25% as the global construction materials industry picks up.
CDE Global in Cookstown, which employs 150 people, said demand was growing around the world for its sand and aggregate cleaning equipment for construction, quarrying and mining.
Marketing manager Peter Craven told the Belfast Telegraph it also hoped to increase the headcount at its US office to 15 during the year ahead.
And he said turnover should reach "the low £40millions" during 2015, from £32m a year earlier.
Mr Craven said the company - which has offices in India, Brazil and the US - was unperturbed by market turmoil.
This month saw some mining shares suffer their biggest back-to-back weekly losses in four years. But yesterday, companies such as Anglo American and Glencore were among the biggest risers on the FTSE 100 share index.
Mr Craven said: "We have probably experienced very little effect from the recent events because they tend to take a little bit longer to follow through.
"Mining is an area of our business with significant growth potential, but is relatively small for now and not one that we are supporting turnover with."
The company had, however, "recalibrated" based on some trends, such as the falling price of iron ore. But he said the global construction market remained strong, with demand still healthy for sand and aggregates.
Its markets were also well spread from Great Britain, Europe, the Middle East, India and, most recently, the US.
CDE's machines are used to refine sand and aggregates to use in concrete, including both ready-mix and for roads. Its machinery was able to find a market in tough times as it was aimed at those needing to focus on efficiency and cost savings, Mr Craven added.
The company has now increased its product assembly space by nearly one-third to allow for the production of 60 additional machines every year. It usually produces around 250 a year.
Operations director Raymond Cooke said extending its headquarters was necessary to meet demand.
"We already have the largest campus dedicated to the wet processing of minerals in the world and our expansion plans will necessitate a further development of this infrastructure," he added. "We look forward to consolidating our position as number one in some of our well-established export markets."
The firm, which employs 150 people, recently launched its 2016 graduate recruitment programme.
CDE Global will be looking for 10 graduates for roles including business development, electrical engineering, product design and development and technical engineering.
Mr Cooke said the graduate places were "fantastic" openings and also offered opportunities for travel.
"In this year alone, we have sold equipment as far afield as the US and Canada, Brazil, Australia, India, Iceland and Sweden, to name a few," he said.
