What DST actually is
DST is Losberger De Boer's trade name for shelter modules built from drop-stitch fabric — two coated fabric faces joined by tens of thousands of internal threads, which hold the panel flat and rigid under pressure. The construction is generic: the same fabric family is used in paddleboards, boat decks and gym mats, and several shelter manufacturers build with it. This matters for procurement because it means 'drop-stitch shelter' is a specification you can tender, not a product you can only buy from one company. What is proprietary to each supplier is their welding quality, engineering, test documentation and delivery record — not the fabric concept.
What actually separates suppliers
Six things decide a technical bid, and none of them is the word 'drop-stitch'. Working pressure: a measured value per wall grade, not a range. Fabric specification: base denier, thread density and coating thickness stated separately — a single gsm figure hides all three. Tensile and tear strength: a third-party test report with the standard and date on it. Fire rating: the standard, the testing body and the report number — EN 13501, NFPA 701 and GB ratings are not interchangeable. Delivery record: a project list with country, quantity and date. And support: spares, repair training and response time, because deployable equipment fails in the field, not the warehouse. Any supplier who cannot produce these on request is asking you to buy a brochure.
When Losberger is the right buy
Stay with the incumbent when procurement rules require a specific certification history, when the quantity is small enough that qualifying a second source costs more than it saves, or when delivery is immediate and no alternative can be qualified in time. Losberger De Boer has built its certification portfolio and delivery record over decades, and for a programme that depends on that history, paying for it is rational. We say this plainly because a comparison that pretends to be even on every axis is not a comparison — it is a sales page.
When a second source makes sense
Qualify an alternative when volumes are large enough that price tension matters, when delivery capacity is a schedule risk, when supply continuity is a stated requirement, or when your configuration differs from the catalogue and you want a manufacturer who builds to your drawing. Large programmes routinely dual-source for exactly these reasons, and qualification usually turns on test data and manufacturing capability rather than brand. Our own position applies to us as much as to anyone: where we lack a third-party test file for a parameter, we say so and do not publish the number — and we would rather lose a bid on an honest answer than win one we cannot document.
How to run a like-for-like comparison
Send both suppliers the same pack: the specification you are working to, the quantities, and the delivery window. Ask each to state which cited standards they can evidence today and which would require new testing — before you build a schedule around either answer. Then compare the six items above line by line. The result is rarely a blowout: it is usually one supplier stronger on certification history, the other on price, capacity or configuration freedom, and the right choice depends on which of those your programme actually needs.
