The ATLANTIS coating is not stainless, but zinc, passivation and epoxy give it C3-H protection without hydrogen embrittlement. Plus why L ≥ tfix + hnom matters. - [The wheel that sold itself “by accident”](https://menet-trend.hu/en/nonox-world/the-wheel-that-sold-itself-by-accident.md) — Two customers waiting at the counter, snow outside, and a box of stainless wheels that had not yet been closed. What followed was a conversation that sold four braked and four unbraked wheels on the spot. NONOX wheels: 100 mm diameter, 160 kg each, swivel, braked or unbraked, from 5990 Ft. - [Hinges](https://menet-trend.hu/en/nonox-world/hinges.md) — Hinges connect two parts so that they can turn relative to one another, and the range runs from tiny instrument covers to industrial gates. NONOX stainless hinges and barrel hinges by material, surface finish, mountability, range of movement and handedness — with the difference between the two explained and nine examples pictured. - [Pulleys on the racecourses](https://menet-trend.hu/en/nonox-world/pulleys-on-the-racecourses.md) — What can a pulley have to do with rowing? More than we would think at first. Beneath an international rowing course, specially designed stainless pulleys guide the wire ropes that hold the buoy rows in place. A long-standing customer's account of building and maintaining them — corrosion, silt, mussels and wasps included. - [Concrete adhesives](https://menet-trend.hu/en/nonox-world/concrete-adhesives.md) — P-NEX is polyester-based, V-NEX is vinyl ester-based, and both bond into solid building materials with no wall plug at all. The six-step method, plus a comparison table covering cracked and wet concrete, hollow brick, underwater use and seismic compliance. - [Blood on the balcony](https://menet-trend.hu/en/nonox-world/blood-on-the-balcony.md) — In the mild early-summer night, creaking and banging breaks the silence of the tenement house into blade-sharp splinters. A dark figure, a weapon-like object, a few drops of blood on the walkway. This story is so real that it could even be true. - [Installing solar collectors and solar panels by replacing the factory mounting frame](https://menet-trend.hu/en/nonox-world/installing-solar-collectors-and-solar-panels-by-replacing-the-factory-mounting-frame.md) — The price of factory mounting frames is rather steep. Replacing them requires some thought, but it is by no means an insoluble task: the fixing must withstand +100ºC and -20ºC, frost, damp and wind, and must stay releasable after 10-20 years. - [Stainless toggle latches](https://menet-trend.hu/en/nonox-world/stainless-toggle-latches.md) — We are modern people. We like solutions that are quick, simple and splendid. Who wants to thread and screw things together nowadays if they don't have to? We like hearing that little metallic snap – the “click-clack and click”. --- HTML:
