Leasing & Hire Purchase
Leasing & Hire Purchase
We offer the financing options leasing and hire purchase exclusively to businesses, commercial operators and self-employed persons for selected products with a net order value of €1,000 or more. Below you will find the key differences between the two forms of financing.
Leasing
With leasing, the product is made available to the lessee for use in return for regular lease payments. The asset is recognized on the lessor’s balance sheet. Lease payments can generally be claimed as operating expenses for tax purposes. These are gross payments, and VAT is charged throughout the entire term. Once the agreed minimum lease term has expired, purchasing the product is generally possible.
Hire purchase
In economic terms, hire purchase is equivalent to an installment purchase. The product is capitalized on the hire purchaser’s balance sheet and depreciated in accordance with the official depreciation tables. Ownership of the asset transfers to the hire purchaser upon payment of the final hire-purchase installment. VAT must be paid in full with the first hire-purchase installment (a pass-through item).
Shipping & Delivery
Shipping & Delivery
We ship our goods either via parcel service or via a freight forwarding company, depending on their size, weight and characteristics. We select the shipping method at our reasonable discretion.
The delivery times stated in the online shop are non-binding estimates, unless a binding delivery date has been expressly agreed in writing. They are based on the information available from our manufacturers, suppliers and logistics partners at the time the order is placed.
A large proportion of the products offered are shipped directly from the manufacturer or from external central warehouses (direct shipment). As a result, delivery times may differ from the stated guidelines. In particular, material shortages, production delays, supply bottlenecks, force majeure or other circumstances for which we are not responsible may result in delivery delays.
Disclaimer:
We accept no liability for delivery delays resulting from circumstances beyond our control. This applies in particular to delays caused by manufacturers, upstream suppliers, transport companies or other third parties. Liability for any resulting damages, in particular indirect damages, consequential damages or loss of profit, is excluded to the extent permitted by law.
Partial deliveries are permitted insofar as they are reasonable for the customer. They will not result in additional shipping costs unless otherwise agreed.
The exact delivery time for an item can be provided individually on request, either before or after placing the order.
Please contact us by telephone at +49 (0)2551 5030 or by email at shipping@strahltechnik-express.de.
If significant delivery delays occur, we will inform the customer without undue delay. Mandatory statutory rights of the customer remain unaffected.

Contracor HBC-32 – Boron carbide Venturi push-in nozzle for blast hose with an ID of 32 mm
The Contracor HBC-32 is a long Venturi push-in nozzle for professional pressure blasting systems with a sandblasting hose featuring an ID of 32 mm. It is designed for high air and abrasive throughput and is particularly suitable for intensive blasting work with highly abrasive media.
The nozzle core made of boron carbide (B4C) offers very high wear resistance. This makes the HBC particularly economical when using corundum, aluminium oxide, silicon carbide and steel grit. The aluminium casing protects the nozzle core and enables robust push-in installation directly into the blast hose.

Suitable blasting media
✔ Silicon carbide
✔ Steel grit and steel shot
✔ Garnet sand
✔ Slag abrasives
✔ Glass beads
✔ Other dry, free-flowing blasting media
Installation and use
The HBC is inserted into the end of a suitable sandblasting hose with an internal diameter of 32 mm and securely fastened. The attachment must be carried out in accordance with the intended push-in installation. Before each use, check the nozzle, hose and securing mechanism.
Typical applications
✔ Surface preparation in steel construction
✔ Mechanical and plant engineering
✔ Tank, ship and vehicle construction
✔ Corrosion protection work
✔ Blast rooms and mobile construction-site applications
✔ Intensive work with aggressive blasting media
Maintenance and safety
✔ Check the nozzle for cracks and damage
✔ Check the attachment to the hose before each use
✔ Only change the nozzle when the system is completely depressurized
✔ Replace damaged or heavily worn nozzles immediately
✔ Use the prescribed respiratory and abrasive blasting protective equipment
