Stainless Steel Frames and Shelves for Pharmaceutical Production

Why pharmaceutical and cosmetic production needs “special” stainless steel

In pharmaceutical and cosmetic workshops, metal structures are subject to different requirements than in regular warehouse or food areas. Stainless steel frames, shelves, and guards here are part of the quality assurance system: they determine how easy it is to maintain cleanliness, pass audits, and upgrade lines.

“Regular” stainless steel for domestic or general industrial tasks often does not take into account:

• washing and disinfection modes;
• requirements for the absence of “dead zones” and gaps;
• corrosion risks from detergents and disinfectants;
• requirements for repeatability and traceability of products.

Therefore, when designing frames, shelves, and guards for pharmaceutical and cosmetic production in Tashkent, we primarily focus not on the “metal thickness” but on the technology: design, welding, finishing, assembly, and installation.

Typical structures: frames, shelves, guards, auxiliary elements

For pharmaceutical and cosmetic production, stainless steel is most often used to manufacture:

• equipment and line frames – supports for reactors, mixers, dispensers, conveyors;
• wall-mounted and floor shelves – for storing raw materials, containers, and consumables;
• guards and handrails – for areas with height differences, stairs, platforms, hazardous zones;
• frame structures and racks – for panels, screens, control cabinets;
• zoning elements – frames for partitions, screens, curtain systems;
• tables, sinks, racks – as part of food and pharmaceutical equipment.

All these products are formally similar to solutions for food workshops or warehouses, but the differences appear in the details: radii of transitions, types of fasteners, profile orientation, options for closing ends, requirements for disassembly and maintenance.

Key differences in materials: which stainless grades and when they are justified

In real projects in Tashkent, two classes of stainless steel are most often used:

• more affordable austenitic or ferritic grades for auxiliary zones and dry rooms;
• more corrosion-resistant grades for areas with frequent washing and aggressive detergents and disinfectants.

How the material is selected

When calculating according to the specification, we clarify:

• washing and disinfection modes: temperature, type of chemicals, frequency;
• contact with the product or only with containers/packaging;
• humidity and temperature in the area;
• loads (static, dynamic, impact);
• required service life and plans for modernization.

Based on these data, a combination is selected of:

• profiles (square, rectangular, round tube);
• sheet (smooth, chequered, perforated);
• fasteners (stainless, combined, concealed);
• where necessary, elements made of other metals with separation by environment.

It is important to understand: attempts to “standardize” everything on a single stainless grade are not always economically justified. It is often more cost-effective to divide areas by environmental aggressiveness and use different materials and thicknesses.

Design and geometry: how to design for clean areas

Pharmaceutical and cosmetic production imposes increased cleanliness requirements. This directly affects the design of frames, shelves, and guards.

Key differences from “regular” stainless steel:

1. Minimum horizontal open surfaces where dust and condensate accumulate. Where possible, sloped covers, chamfers, and rounded shapes are used.
2. Rejection of complex profiles and “pockets” that are difficult to wash and inspect.
3. Closed tube and profile ends – end caps, full welding, closing elements.
4. Rational joint placement – welds and bolted connections are moved to areas accessible for washing.
5. Disassemblability where it is truly needed – the ability to dismantle individual units without damaging finishes and utilities.
6. Coordination with process engineers and the quality department – heights, passage widths, the ability to clean under structures.

At the calculation stage based on the specification, we often propose refining the initial 3D models or drawings: simplifying joints, changing profile orientation, adding chamfers or radii. This reduces the risk of comments during validation and audits.

Welding, seams, and subsequent treatment: what is critical for pharma

Visually, two stainless steel products may look identical but differ in service life and behavior during washing. The key risk area is the welds.

Welding specifics for pharmaceutical and cosmetic production

• Heat input control – to prevent overheating, deformation, and changes in metal structure.
• Full penetration and absence of undercuts – especially on load-bearing frames and guards.
• Minimization of spatter and build-up – everything that complicates washing must be removed.
• Protection of the weld zone (inside the profile, where necessary) – to prevent corrosion centers from forming.

Weld treatment

After welding, pharmaceutical structures usually require:

• mechanical treatment – grinding, leveling the weld;
• chemical treatment of the weld zone – passivation/pickling to restore the protective layer;
• surface texture leveling – so that the weld does not become a “trap” for contaminants.

Unlike “regular” stainless steel for warehouses, saving on weld treatment here leads not only to a deterioration in appearance but also to corrosion risks and problems during inspections.

Final surface treatment: roughness, polishing, combined solutions

Different areas of pharmaceutical and cosmetic production may require different levels of final surface treatment.

Treatment options

• Ground (satin) surface – optimal for most frames and guards: easy to clean, non-glare, aesthetically pleasing.
• Polished surface – used where minimal roughness and easier washing are critical.
• Combined solutions – load-bearing elements are ground, contact and visible areas are polished.

When calculating according to the specification, we additionally clarify:

• appearance requirements (especially for areas with visitor routes or showcase zones);
• modes of mechanical load and possible impacts (polished surfaces are more sensitive to scratches);
• type of cleaning equipment and washing frequency.

The choice of finish directly affects both the production technology (number of grinding/polishing passes) and the final cost.

How we work with specifications: from customer drawings to production-ready designs

The contract manufacturing format for stainless steel for pharmaceutical and cosmetic production implies that the starting point is the customer’s specification.

We can work in several scenarios:

1. Finished drawings and 3D models

   • we analyze the design for manufacturability;
   • if necessary, we propose changes to joints, welding, and metal thickness;
   • we approve the final version and launch it into production.

2. Sketches, diagrams, photos of existing solutions

   • together with process engineers and quality engineers, we form the specification;
   • we select materials and profile sections;
   • we prepare working drawings for laser cutting, bending, and welding.

3. Adapting existing solutions to new premises

   • we take into account actual dimensions and utility constraints;
   • we recalculate loads and fixing points;
   • we propose modular and disassemblable options.

At each stage, we fix the approved version of the specification, which determines the calculation, lead times, and production organization.

What affects the price of stainless steel frames and shelves: factor breakdown

We do not provide specific prices — they vary greatly by project. Below are the key factors considered in the calculation.

When contacted, we perform a calculation based on the specification, where all these factors are transparently taken into account.

Contract manufacturing lead times: from single items to series

Lead times depend on volume, complexity, and production load, but there is a general planning logic.

The stages usually look like this:

1. Specification analysis and clarifying questions – clarification of materials, loads, and surface requirements.
2. Process engineering – if necessary, refinement of the design for laser cutting, bending, and welding.
3. Calculation and approval – fixing volume, lead times, and delivery stages.
4. Manufacturing of prototypes or pilot batch – relevant when launching a new line.
5. Series production and shipment – according to the agreed schedule.

Lead times are affected by:

• product complexity and number of unique items;
• need for prototypes and testing;
• availability of the required grade and thickness of material in stock or from suppliers;
• installation schedule and access to the site in Tashkent or the regions.

The more accurate and complete the initial specification, the easier it is to predict real lead times and avoid delays.

Typical mistakes when ordering stainless steel for pharmaceutical workshops and how to avoid them

1. Transferring “warehouse” solutions to clean areas

Using designs intended for warehouses or general industrial premises without considering cleanliness and washing requirements leads to rework and audit comments.

2. Underestimating the impact of detergents and disinfectants

Choosing a more “budget” stainless steel grade without considering the chemistry and washing temperature results in early corrosion, discoloration, and the need for replacement.

3. Lack of coordination with process engineers and the quality department

Frames, shelves, and guards are designed only from a mechanical standpoint, without considering personnel routes, cleaning, and inspections. The result is inconvenient passages and hard-to-reach areas.

4. Overly complex design without real necessity

An excessive number of ribs, inserts, and decorative elements increases cost and complicates washing without adding value for production.

5. Saving on weld and finish treatment

The product may look acceptable externally, but untreated welds become centers of corrosion and contamination buildup.

6. Incomplete specification

Lack of data on loads, operating mode, environment, and surface requirements leads to multiple approvals and schedule shifts.

7. Ignoring future modernization

Frames and guards are made “for the current machine” without allowance for dimensions and without the possibility of adapting to new equipment.

Working through a detailed calculation based on the specification and early involvement of process engineers and quality engineers helps avoid most of these mistakes.

FAQ on stainless steel frames and guards for pharmaceutical and cosmetic production

1. Can the same solutions as for food workshops be used?

Partially yes, but pharmaceutical and cosmetic production often imposes stricter requirements on cleanliness, traceability, and documentation. The design and surface treatment level usually have to be enhanced.

2. Is it mandatory to make all structures entirely from stainless steel?

Not always. Auxiliary areas without product contact and aggressive washing can sometimes be reasonably made in a combined version. This is a matter of calculation based on the specification and risk assessment.

3. Which is better: welded or demountable structures?

For clean areas, welded solutions with a minimum number of fasteners are more often chosen. Disassemblability is used where frequent reconfiguration or dismantling is truly needed.

4. Can existing structures be upgraded?

In many cases, yes: reinforcing, adding guards, replacing individual elements with stainless ones, adding screens. But sometimes it is cheaper and safer to manufacture new frames to current requirements.

5. How to take into account auditor and inspector requirements in design?

The best option is to involve a quality engineer and process engineer at the specification stage. We take into account their comments on geometry, washability, types of joints, and surface finish.

6. Is it possible to start with a small batch or a single area?

Yes, projects often start with a pilot area or a single line: design and treatment solutions are tested and then replicated to other zones.

7. What data are needed for a preliminary calculation?

At a minimum – dimensions, loads, washing modes, and surface requirements. The more detailed the specification, the more accurate the calculation and lead time forecast.

8. Do you work only with finished drawings?

No, full support is also possible: from sketches and on-site measurements to the development of working documentation for contract manufacturing.
