A spring has so many variables (material type, thickness, etc.) that it is almost impossible that a standard spring will be used in your construction. That is why we manufacture almost all springs on order; this way Roveron is not left with expensive outdated stocks. We do offer a range of compression springs directly in our webshop.
Once a client orders the same article more often, Roveron will (possibly in consultation with the client) keep the article in stock.
