International standards
Our products are manufactured to CE, TSE and ISO 9001 standards and meet the safety expectations of learning environments.
Quality & Certificates
For us, quality begins not at the final check but with the choice of the first board.
At Sırasan, quality is not a slogan but a production discipline. We show the same care at every stage, from raw-material selection to assembly, and build our products to withstand years of intensive use in educational environments.
Our products are manufactured in line with national and international standards; we guarantee the health-safety of the materials and paints we use and the durability of frames and joints through independent certificates and staged in-house controls.
- CE, TSE and ISO certified production
- Tested, long-lasting durability
- Staged control from raw material to shipment
Our Certificates & Standards
Our products are certified against national and international standards — from safety and durability to environmental responsibility. They are manufactured in compliance with the certificates and marks below.

Our Quality Approach
We safeguard quality not at a single stage but at every step of production. From raw-material selection to shipment, each process is monitored and recorded against defined control points.
Tested durability
They are designed for intensive, long-term use; bodies and joints are tested against demanding conditions.
Respect for people and environment
We use materials and paints safe for human health and manage production waste responsibly.
Staged quality control
Every product passes through staged quality control, from raw material to shipment.
What the certificates mean for a buyer
On most manufacturer sites a certificate list is just a row of logos that tells the buyer very little. Yet each document has a concrete meaning for a purchasing decision. The table below sets out what the standards our products are manufactured to actually mean for a school or institutional buyer.
| Document / standard | What it covers | What it means for you |
|---|---|---|
| CE | Conformity with EU health, safety and environmental requirements | The product is made to a defined safety framework; the baseline mark sought in export and international school projects |
| TSE | Conformity with Turkish Standards | The document most often requested in public procurement and technical specifications |
| ISO 9001 | Quality management system | Quality belongs to the process, not to a single item — the second batch of the same order comes out to the same standard |
| Domestic Goods Certificate | Confirms domestic manufacture | May create a price advantage in public tenders; whether it applies is stated in the specification of the tender concerned |
The most frequently misunderstood of the four is ISO 9001. It is not a product certificate; it is a system certificate that defines how a product is made, at which stages it is checked and how a problem is traced when one arises. In school furniture that distinction matters, because what a school buys is not one desk but hundreds of desks that must be identical to one another.
At which stages do we check quality?
Leaving quality control to a single final inspection means catching the fault at the most expensive point — after production is finished. We therefore distribute the checks along the production line.
| Stage | What is checked | What it catches |
|---|---|---|
| Raw material intake | Panel, profile and paint material against specification | Wrong or substandard material entering the line |
| Cutting and forming | Dimensional tolerance, edge accuracy | Deviations that would leave gaps at the joints |
| Welding and assembly joints | Strength and alignment of joints | Frames that would loosen or rock over time |
| Surface treatment | Coverage of the electrostatic powder coating and oven curing | Thin coating, colour variation, early scratching |
| Assembly | Part fit, behaviour of moving parts | Mismatches that would only be noticed on site |
| Pre-dispatch | Quantity, colour and height grade; packaging | The wrong product leaving the works, transit damage |
Will the colour match when a second batch arrives?
This is the issue schools meet most often and discuss least. Batches produced at different times can differ slightly in tone; this follows from the paint batch and the curing conditions and applies across the industry.
Three things help in practice. First, order for the whole school in one batch — this is the only certain way to guarantee colour consistency. Second, if the purchase is phased, fix the RAL code with the first order and quote the same code every time afterwards. Third, plan phased distribution by floor or by block: when two different batches never sit in the same room, a difference in tone goes unnoticed.
If you tell us before ordering that the purchase will be phased, we build these three points into the plan from the outset.
What should you ask a supplier?
This section is not written to persuade you to work with us but to help you ask the right questions. You should get a clear answer to the six questions below from any manufacturer you approach — including us.
- Is the product actually made by you? A manufacturer and a supplier are not the same thing. Buying from the manufacturer makes changes to dimension, colour and configuration possible; buying through an intermediary keeps you inside the catalogue.
- Can you manufacture to my specification? In public procurement the ability to adapt the product to the specification is decisive.
- Can I have the documents with the offer? Certificates should be seen at the offer stage, not after the order.
- How do spares and service work? What happens when a single foot pad or panel is needed five years later should be asked on day one.
- Is delivery included in the price? This is the item most often missed when comparing offers; with us delivery appears as a separate line in the quotation and is not included in the product price.
- Who carries out the installation? The scope of installation and who performs it should be in writing before the order.
You can find the technical specifications and material comparisons of our products in our product catalogue, and get in touch to discuss your project. Project surveys are free of charge.
