2nd chance items
Among the items, you may also find second-hand items. These are returned products or products left over after construction has been completed. These products are certified. By ordering these, you'll help the environment and save money on your purchase! We arrange transport in the same way as new products.
Do you already have a purchasing account?
Once you have completed your project, you will also see, per project or in total, what has not yet been used and is in "stock".
You can then assign this to another project or sell it on Qonstruct as a second chance item.
Use the form, set your price, and we'll take care of the rest, including transport from your location to a buyer or your assigned project. If you'd like to remove it from your location beforehand, we can pick it up and store it for you.
Do you have a purchasing account and only want to purchase a second-hand item?
You can do this simply by ordering it as a new product.
Do you have leftovers from previous projects?
You can also submit these using this form. We do, however, ask that you include the article numbers and specifications so they can be compared to new items. If you don't have article numbers or specifications, your leftovers will end up in the "general leftovers" section.
Vintage
You can also find "vintage" products: old fireplace mantels, doors, window frames, and much more. These don't have modern-day colors, but they enhance your home with authentic materials!

This form is intended for adding one or more articles to the file for the first time only.
After we've discussed various matters such as transport, storage, locations, billing, etc., we'll provide you with a login account so you can manage your items yourself from that point on.
If you already have a Purchasing Company account and the item is in your current inventory, you can easily allocate this inventory item to the sales file without further consultation.
Second chance items are only for business offers. Private offers are not listed.
If a second-chance item is sold, we will contact you or the other party so that you can invoice yourself or we will credit you with the amount received.
Transport
We will charge the recipient for transportation unless you are willing to arrange transportation yourself.
Storage
If necessary, we can also remove items from the storage location in advance. We charge a competitive storage rate for this. Naturally, you only pay for the space used. We store items up to a maximum height of 8 meters (indoors) and unlimited height outdoors. Items on pallets may weigh a maximum of 5,000 kilos/square meter.
Vintage items
Old building materials such as doors, windows, fireplace mantels, etc., have their own place in the database. This is also accessible to private buyers.
