Upcoming Mainboard IPOs – Fresh Investment Opportunities

The Indian stock market is gearing up for some noteworthy public issues as we step into March 2026. Among the most talked-about are two mainboard IPOs  — Rajputana Stainless Limited and Sedemac Mechatronics Limited. For both new and seasoned investors, these public offerings bring fresh opportunities to participate in India’s growth story. Let’s break down what you need to know in a friendly and easy-to-understand way.

Rajputana Stainless Limited IPO — A Steel Story

Key Details

• IPO Open: March 9, 2026
• IPO Close: March 11, 2026
• Price Band: ₹116–₹122 per share
• Lot Size: 110 shares (minimum application)
• Listing: Proposed on BSE and NSE
• Issue Size: Around ₹255 crore (fresh + offer for sale) 

Rajputana Stainless Limited is a well-established stainless steel products manufacturer with decades of experience. With roots stretching back to 1991, the company has steadily expanded its footprint in both domestic and international markets.

What the Company Does

Rajputana Stainless produces a wide range of stainless steel offerings such as billets, forging ingots, rolled bars (both black and bright), flat products, patti and other ancillary items. These products serve various industries including aerospace, oil & gas, defence, automotive, aviation and precision engineering.

The company’s products are not just sold domestically — they’re also exported to regions like the UAE, USA, Turkey, Kuwait and Poland, helping establish its global reach.

Why This IPO Matters

Here’s what makes the Rajputana Stainless IPO interesting:

• Expansion Plans: A portion of the funds raised will be used to set up a new manufacturing facility for stainless steel seamless pipes, which could help enhance product variety and capacity.
• Debt Repayment: The company is also allocating funds to repay or prepay some of its outstanding borrowings, which can strengthen its financial health.
• Corporate Purposes: The remaining capital will be used for general corporate needs. 

This IPO is a mix of a fresh issue (new shares being created) and an offer for sale (existing shareholders selling some of their stake). This means investors can potentially get in at an early stage while the company continues to grow.

Sedemac Mechatronics Limited IPO — Tech Meets Mobility

 Key Details

• IPO Open: March 4, 2026
• IPO Close: March 6, 2026
• Price Band: ₹1,287–₹1,352 per share
• Lot Size: 11 shares
• Issue Size: About ₹1,087 crore
• Listing: Expected on BSE and NSE

Sedemac Mechatronics has carved out a strong niche as an electronics and mechatronics provider, especially in the automotive and industrial sectors. Located in Pune, this company specializes in designing and manufacturing advanced electronic control units (ECUs), powertrain controllers and related products.

What Sets Sedemac Apart

Sedemac is not just another tech company — it operates in a space that is crucial to vehicles and industrial automation. Its products are integral to engines, powertrain systems and generator units, and the business has strong relationships with original equipment manufacturers (OEMs) in the mobility ecosystem.

The company is considered a leader in components such as:

• ISG ECUs (Integrated Starter–Generator Controllers)
• Engine Control Units
• Motor Control Products 

This positioning gives Sedemac an edge in what many analysts call a niche tech play in the auto ancillary space.

IPO Structure and Investment Perspective

Uniquely, the Sedemac IPO is structured as a 100% Offer for Sale (OFS). That means the company itself won’t receive the IPO proceeds — instead, existing shareholders will sell part of their holdings through this public offering.

A retail investor who wants to apply for this IPO must invest a minimum amount of around ₹14,872 (at the upper price band), making it accessible for many individual investors.

On the investment front, brokers have highlighted Sedemac’s healthy margins, efficient balance sheet and strong growth prospects through technology-intensive products and OEM partnerships.

However, it’s worth noting that since this is a selling shareholders’ offer (OFS), the company doesn’t get fresh capital for future expansion projects. Investors should factor this into their decision-making process.

Final Thoughts

These two IPOs offer distinct experiences for investors:

• Rajputana Stainless – A traditional manufacturing company raising fresh capital to expand production and reduce debt. 
• Sedemac Mechatronics – A tech-oriented firm offering a chance to invest alongside early stakeholders in a specialized auto and industrial electronics business. 

Both IPOs illustrate how India’s mainboard market continues to evolve, blending classic industrial plays with tech-driven enterprises. Whether you’re a long-term investor or an active trader, these offerings are worth your attention
