This is one of those questions that no one will will tackle because there are other factors that weigh into this type construction: Angle of lift, How will the new beam be supported, Is the foundation sufficent, indoors vs outdoor ect. I'm afraid we do not have enough information to safely answer your question.
What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts
To determine the appropriate size I-beam for spanning 25 feet with a load of 7,000 lbs, a structural engineer typically considers factors such as the load type (uniform or point load), beam material, and safety factors. Generally, a W8x10 or W10x12 beam might suffice for this application, but precise calculations involving deflection limits and local building codes are crucial. It is essential to consult with a structural engineer for an accurate assessment tailored to specific conditions.
Purlins are used on double roofs. They effectively reduce the span of the rafters and limit their size to ecenomical sections.
use 400x400mm with a rebars of 8-16mm dia. for 4-5m span.
the beam has a total volume of 60ft 3 what is the maximium horizontal gap that the beam can span

What size steel I beam do I need to span a 32 feet garage with a floored storage above and no posts
To span a distance of 20 feet, a lumber beam of at least 2x10 size is typically needed for adequate support.
It depends on the roof load and the actual clear span. Off hand, I would guess htat you haven't given this much thought. A rule of thumb for a steel truss is one inch per foot of span or in your case 40 inches. If you want to use a steel I-beam, you can get that from a good municipal library from the steel beam institute, but you are going to need a crane to place it. Dieter in Cincinnati

Tell us the size of the span, and what it is made from, and we may be able to get you an estimate. A single 6 foot board is 5 seconds, a 300 foot long concrete and steel span takes a little longer.
The size of the beam needed to span 8 meters depends on several factors, including the type of material (wood, steel, concrete), the load it will support (live load and dead load), and the beam's design (e.g., continuous, simply supported). For example, a steel I-beam may be smaller than a wooden beam for the same load. It's essential to consult structural engineering tables or a professional engineer for specific calculations and recommendations based on the project's requirements.

2X8 set 16 inch on center.
The size of the beam needed to span 10 feet for roof support depends on various factors, including the type of material (wood, steel, etc.), the load it will carry, and local building codes. For a typical wooden beam, a common choice might be a 2x10 or 2x12, but calculations based on specific load requirements and spacing are essential. It's advisable to consult a structural engineer or local building codes to determine the exact specifications for safety and compliance.
You will have to have an engineer spec that beam for you. You will save yourself time and money by cutting the span with a column.
